Abstract:

Abstract The cationic thorium(IV) complexes [Th{Ph2P(O)CH2CH2P(O)Ph2}2(NO3)3]NO3 and [Th{Ph2P(O)NP(O)Ph2}3(dmso)2]NO3 have been synthesized by reactions of Th(NO3)4 · 5H2O with bis(diphenylphosphino)ethane dioxide, Ph2P(O)CH2CH2P(O)Ph2 (L1), or ammonium bis(diphenylphosphoryl)amide, (NH4)[Ph2P(O)NP(O)Ph2] (NH4L2), and subsequent recrystallization from dimethyl sulfoxide. The products have been studied spectroscopically and by X-ray crystallography. The thorium atom is ten-co-ordinate in the [Th(L1)2(NO3)3]+ cation with a coordination sphere which does not match one of the idealized polyhedra for ten-coordination. Th-O bonds have been found in the range between 2.342(3) (phosphine oxide) and 2.599(4) A (nitrate). An eight-coordinate thorium atom is found in the [Th(L2)3(dmso)2]+ cation. The almost ideal square-antiprismatic environment of the metal is occupied by oxygen atoms with Th-0 bond lengths between 2.363(6) and 2.392(11) Å

Abstract:

The solvent extraction is one of the most common method for separating Th from solution. Primary amine has higher selectivity for the extraction of Th(IV) than U(VI) and RE(III) in sulfate media. N1923 (a primary aliphatic amine with amino nitrogen linked to a secondary carbon consisting of branched alkyl groups in C19–23 range) is commonly used to extractTh. At room temperature using 0.1M N1923 amine as solvent in this work, the results showed thatthorium maximum extraction capacity was about 2.5g/L with concentration of sulfuric acid in the aqueous phase was 1M and for 3 minutes shaking. At room temperature for 3 minutes shaking the best conditions for scrubbing processwas using the mixture of acids H2SO4 0.2M and HNO3 0.1M, result inover 75%, Th was scrubbed in the aqueous phase only 0.7%. The separation of Th from leachate of monazite sulphation process was carried out on a multistage continuous flow extraction device (12 boxes), the thorium purity was 98%. Therefore, the use of amine solvents can purify thorium from rare-earth solutions in a sulfate medium

Abstract:

Abstract Thorium, as an important radioactive element, is widely present in nature, and its accompanying environmental pollution is also serious. Extracellular polymeric substances (EPS) are commonly found on the surface of microbial bodies and have strong adsorption capacity for metal ions. In this study, four methods were used to extract EPS from indigenous bacteria of rare earth tailings and to determine the best extraction method. The extracted EPS was applied to treat Th4+, and the changes in functional groups and composition of EPS were investigated. The results showed that the ultrasonic method was more efficient than other methods. The best removal efficiency was observed at pH 3.5, Th4+ concentration of 20 mg/L, and EPS dosage of 30 mL at 25 °C. After 9 h, the adsorption process reached equilibrium with a maximum removal efficiency of 75.93% and a maximum theoretical adsorption capacity of 25.96 mg/g. The Th4+ removal process was consistent with the Langmuir and Freundlich adsorption isotherms and the kinetic data were consistent with the pseudo-second-order kinetic model, which is mainly based on chemisorption. Amide I and amide II of proteins, C–H from aliphatic, as well as O–H and C = O from carboxylic acid play important roles in the adsorption process.

Abstract:

Simple synthetic modulation based on thorium nitrate and tris((4-carboxyl)phenylduryl)amine (H3TCBPA) gives rise to a new thorium-based metal-organic framework, Th-TCBPA, which features excellent hydrolytic and thermal stabilities. Incorporating electron-rich TCBPA3− linkers...
