Resumo: Ácido itacônico (AI) é um produto químico promissor que tem uma ampla gama de aplicações e pode ser obtido em grande escala por processos fermentativos. A separação de AI a partir do caldo fermentativo tem um impacto considerável no custo total da produção. Por conseguinte, a procura de processos para a recuperação de ácidos orgânicos com alta eficiência e baixo custo é um dos passos chave para a substituição de produtos de base petroquímica. Apesar dos avanços biotecnológicos em frente aos processos fermentativos, o principal obstáculo ainda é a separação e purificação. Uma revisão sobre os principais métodos de separação foi realizada nesse trabalho e fomentou as diretrizes dessa investigação. Um dos métodos mais comuns para a separação de ácidos orgânicos envolve a precipitação e ressolubilização (regeneração). Os estudos sobre a precipitação de AI são dificilmente encontrados na literatura, embora estejam bem desenvolvidos. Neste estudo, os dados da solubilidade de itaconato de cálcio foram determinados de modo a avaliar o potencial de precipitação de AI. O processo foi muito dependente da temperatura, com recuperação de 88 a 97% na faixa de 20 a 80°C. A separação de AI a partir de soluções aquosas usando resinas comerciais de troca iônica fortemente básicas foi outra investigação realizada. A adsorção foi investigada para determinar os efeitos da concentração inicial de AI, pH e temperatura. As isotermas clássicas de Freundlich e Langmuir e a cinética de pseudo-segunda ordem foram utilizadas para calcular os parâmetros de adsorção. Um modelo matemático simplificado foi desenvolvido e validado com dados experimentais de uma coluna de leito fixo. Durante os experimentos, um método analítico foi desenvolvido para a determinação da concentração de AI em solução aquosa. Palavras-chave: Recuperação de Ácidos Orgânicos, Ácido Itacônico, Análise, Precipitação, Adsorção.
Abstract: Itaconic acid (IA) is a promising chemical product, which has a wide range ofapplications and can be obtained in large scale by fermentative processes. Theseparation of IA from fermented broth has a considerable impact in the total cost ofproduction. In that way, the search for high efficiency and low cost processes oforganic acids recovery is one of the key steps to the replacement of petrochemicalbasedproducts. Despite the important biotechnological advances in fermentativeprocesses, the biggest remaining obstacles remain being the separation andpurification. In this work, a review of the main separation methods has been doneshowing that the most common methods of organic acids separation involvesprecipitation and regeneration. Studies about IA precipitation are rare in the literature.In this study, the data about calcium itaconate solubility were determined as a meansto evaluate IA precipitation potential. The process is dramatically dependent oftemperature, with recovering yields ranging from 88 to 97% at temperatures of 20 to80ºC. Another investigation made was the IA separation from aqueous solutionsusing strongly basic commercial ion-exchange resins. This adsorption method wasinvestigated in order to determine the effects of IA initial concentration, pH andtemperature. The classical isotherms of Freundlich and Langmuir and a pseudosecondorder kinetics were used to calculate the adsorption parameters. A simplifiedmathematical model was developed and evaluated with experimental data obtainedfrom a fixed bed column. During the experiments, an analytical method wasdeveloped to determine the concentration of IA in aqueous solution.Key words: Organic Acids Recovery, Itaconic Acid, Analysis, Precipitation,Adsorption.

Повний текст джерелаNitric acid is widely used in spent nuclear fuel reprocessing, especially in PUREX process (Plutonium and Uranium Refining by Extraction). This process is based on liquid-liquid extraction of Uranium (+VI) and Plutonium (+IV). Plutonium is separated from Uranium by addition of Uranium (+IV) in nitric acid, stabilized by hydrazinium ion (N2H5+). However, the radiolysis of nitric acid, result of the presence of alpha emitting radionuclides, generates in solutions free radicals and molecular species. These species are capable of modifying the redox state of actinides and reacting with hydrazinium ions.The aim of this work is to reveal the chemical and physical-chemical parameters that may modify the oxidation states of Uranium and Plutonium in nitric acid solutions. Among these parameters, the role of nitrous acid and hydrogen peroxide, generated by radiolysis of the nitric acid, is very important. The objective is to redefine the kinetics of formation of hydrogen peroxide and nitrous acid during alpha radiolysis of nitric acid / sodium nitrate, as a function of three parameters: acidity, nitrate concentration and the linear energy transfer of ionizing radiation.It was shown that the formation of hydrogen peroxide decreases with increasing nitrate ions concentration and increases greatly with the acidity of the solution (until it reaches a stationary value for an acidity of 0.2 mol L-1). The formation of nitrous acid is promoted by the increase the nitrate ions concentration. It was observed that G(HNO2) varies according to two trends. The first one in dilute nitrate solutions and the second in concentrated nitrate solutions. These two trends reflect the direct and indirect radiolytic phenomena, modifying the mechanisms of formation of HNO2. The study of acidity has showed that the formation of H2O2 and HNO2 is promoted by increasing the concentration of hydronium ions, until it reaches a steady state value for an acidity close to 0.2-0.5 mol L-1.Furthermore, the effects induced by ionizing radiation (,,,…) on formation yields of H2O2 and HNO2 were studied. It has been shown that the linear energy transfer (LET), between 0.2 keV µm-1 (characteristic of a gamma radiation) and 130 keV µm-1 (characteristic of the alpha radiation emitted by radioactive decay of actinides), has a significant influence on formation yield of H2O2 and HNO2. It was observed that the impact of nitrate ions on the formation yield of H2O2 becomes more pronounced when the LET increases. Conversely, the impact of nitrate ions which promote the formation of HNO2, decreases when the LET increases.Based on these results, two parametric equations were developed. The advantage of this parameterization is to predict the radiolytic yields formation of H2O2 and HNO2 according to chemical conditions ([NO3-] ≤ 4 mol L-1 and 10-5 mol L-1 ≤ [H+] ≤ 4 mol L-1) and the nature of the beam (LET between 0.2 to 130 keV µm-1).The purpose of this study is to predict the quantity of H2O2 and HNO2 formed by radiolysis of HNO3/NaNO3, during the different steps of the nuclear fuel reprocessing

. The aim of the study is to enhance the ozonation efficiency in treating the waste dye solution. The effects of pH, initial dye and initial ozone concentrations and the concentration ratio of initial H2O2 to initial O3 on color and COD removals were investigated. Also, the kinetics of O3-dye reaction in the presence of H2O2 was approximately determined. As a result of the experimental study, it was seen that an increase in the initial dye concentration at a constant pH and initial ozone concentration did not change the COD % removal significantly, from a statistical analysis of the data. The results obtained at pH values of 2.5 and 7 gave higher oxidation efficiencies in terms of color and COD removals compared to those at pH of 10. The best initial molar ratio of H2O2 to O3 was found to be 0.5, which yielded highest treatment efficiency for each pH value studied. The results of the excess dye experiments suggest that the ozonation of Acid Red 151 follows an average first order reaction with respect to ozone at pH=2.5 and pH=7 whereas it is around 0.56 at pH=10. By Initial Rate Method, the orders with respect to individual reactants of O3 and dye were determined as one, the total order of the reaction being two for all the studied pH. As a conclusion, a further study of the peroxone process at a pH of 10 can be recommended to determine the reaction kinetics and mechanism at this pH, where radicals play an important role.

Повний текст джерелаSince the nitrate ion is essentially non-complexing with the ferric ion, the presence of chloro complexes of the ferric ion in FeCl$ sb3$-HCl etchant solutions was investigated. The FeCl$ sb2 sp+$ and FeCl$ sb3 sp0$ complex ions were found to constitute the majority of ferric species at all concentrations, and their respective enhancing and inhibiting effects incorporated into a rate equation: = A {m sb{FeCl sbsp{2}{-}} over 1 + 0.25m sb{FeCl sbsp{3}{0}}} here m$ sb{ rm i}$ is the molality of species i. The rate constant, A, was found to fit an Arrhenius plot for a temperature range of 30-50$ sp circ$C.
Experiments performed with etchants containing both the chloride and nitrate ions showed etch rates increasing uniformly as the chloride fraction of total anion increased. The FeCl$ sb2 sp+$ complex continues to exhibit an enhancing effect in these solutions, but at the conditions chosen the concentration of FeCl$ sb3 sp0$ remains constant. The FeCl$ sp{2+}$, however, appears to inhibit the etch rate.

Повний текст джерелаTiivistelmä Sinkki on yleinen metalli, ja sillä on keskeinen rooli sinkittyjen terästuotteiden, paristojen ja jopa lannoitteiden valmistuksessa. Sen tuotanto perustuu sinkkipitoisten mineraalien rikkihappoliuotukseen, muodostuneen prossessiliuoksen puhdistukseen ja lopulta metallisen sinkin elektrolyysitalteenottoon. Tässä työssä kehitettiin termodynaaminen malli teollisesti tärkeälle ZnSO₄-H₂SO₄-H₂O -systeemille. Malliparametrit määritettiin kirjallisuudessa esitetyistä tuloksista ja tässä työssä tehdyistä uusista jäätymispiste- ja tiheysmittauksista. Käyttämällä kaupallisia Gibbsin energian minimointialgoritmiin perustuvia ohjelmistoja, kuten ChemSheet tai FactSage, tässä työssä kehitetyllä mallilla voidaan helposti kuvata sinkkisulfaattipitoisten vesiliuosten faasitasapainoja ja laskea systeemin termodynaamisia ominaisuuksia. Malliin sisällytettyihin ominaisuuksiin kuuluvat systeemin komponenttien aktiivisuudet, entalpiamuutokset, lämpökapasiteetit sekä tiheydet laajalla lämpötila-, paine- ja rikkihapon pitoisuusalueella. Liuoksen epäideaalisuutta kuvattiin Pitzerin ioniaktiivisuusmallilla. Työssä sinkkisulfaattiliuoksille kehitettyä mallia testattiin kahdessa sinkintuotannon kannalta keskeisessä tapaustutkimuksessa. Amorfisen piidioksidin saostumista vahvahappoliuotuksen aikana tutkittiin kokeellisesti ja laskennallisesti. Amorfisen piidioksidin liukoisuus prosessiliuokseen ennustettiin onnistuneesti. Kipsinpoistoprosessin tutkimusta varten mallia laajennettiin lisäämällä siihen Ca²⁺-ioni. Mallilla laskettiin kipsin liukoisuus prosessiliuokseen. Saadut tulokset vastasivat hyvin käytännössä havaittuja arvoja. Tutkimuksen tuloksia on suoraan hyödynnetty sinkintuotantoprosessin ymmärtämisessä. Ne myös mahdollistavat jatkossa edistyneempien työkalujen kehittämisen niin prosessin hallintaan kuin tutkimukseenkin

Повний текст джерелаSpherical micelles were formed when the PAA content in the copolymers was relatively higher. The PS core radii scaled as R$ sb{ rm core} sim$ N$ sb{ rm PS} sp{0.4}$ N$ sb{ rm PAA} sp{-0.15}$, where N$ sb{ rm PS}$ and N$ sb{ rm PAA}$ are the lengths of the PS and PAA blocks, respectively. The PAA corona shell dimensions were also studied. As the PAA content in block copolymers decreased, the morphology of the aggregate changed progressively from spheres to cylinders, to vesicles and lamellae, and eventually to compound micelles. The effects of the initial copolymer concentration and the addition of homopolystyrene on the aggregate morphology were also examined. The aggregate morphology appears to be controlled by a force balance mainly involving three aspects, i.e. the stretching of the PS chains in the core, the surface tension between the PS core and the solvent, and the inter-corona chain interactions.
The aggregate morphology can be controlled by adding ions in micro-molar (HCl, NaOH, CaCl$ sb2$ or Ca(Ac)$ sb2$) or milli-molar (NaCl) concentrations. In addition to the various morphologies obtained by changing the copolymer composition, large compound vesicles, a new morphology, can be obtained from a single block copolymer. The morphogenic effect of different added ions on the crew-cut aggregates can be ascribed to the changed inter-corona chain repulsive interactions, due to neutralization, protonation, ion-binding, and screened electrostatic field, etc. The range of morphologies obtained in this study is believed to be unprecedented for a block copolymer self-assembly system in low molecular weight solvents.

Повний текст джерелаFor systems containing glycylglycine, the results show that the nature of the anion has a major effect on the activity coefficients of glycylglycine. Comparison of activity coefficient data for glycylglycine with literature data for glycine, both in aqueous NaCl solutions, indicates that the effect of the electrolyte is larger for the peptide than for the amino acid. For the peptide, in all cases, the effect of the electrolyte is more important at low molalities of the electrolyte. The Wilson equation was used to correlate the activity coefficient data obtained. The correlation results were satisfactory for the region of concentrated electrolyte. For systems of DL, alpha-aminobutyric acid in electrolyte solutions, the cation was found to have a significant effect on the activity coefficients of DL, alpha-aminobutyric acid. There exists a distinctively different tendency of the activity coefficients in the dilute and in the concentrated regions of electrolyte in the presence of DL, alpha-aminobutyric acid.
