Abstract:
Abstract Zinc chlorlde-diphenylamlne reagent, whose use has been reported for the detection of organochlorine insecticides by thin layer chromatography, was further studied for its ability to detect the organophosphorus insecticides phorate, phosphamldon, DDVP, and phosalone and the carbamate Insecticides carbaryl and aldicarb. These Insecticides give Intense blue-green spots with this reagent. The procedure can be applied to the detection of the insecticides in biological materials and thus has a potential use in forensic toxicology

Abstract:
Abstract A Griess reaction that has been used to detect organic compounds containing an aromatic amino group was used to detect organophosphorus compounds containing a nitrophenyl group, such as ethyl parathion, methyl parathion, and fenitrothion. On reduction with stannous chloride in HCI–water (1 + 1), these compounds give respective amino derivatives, which are further diazotized and coupled with 1-naphthylamine to give intense pink–orange spots. This reagent also gives a bluish to violet spot with p-nitrophenol, a metabolite of fenitrothion. The procedure can be used to detect these insecticides in biological materials in forensic toxicology.

Abstract:
Ten newly synthesized organophosphorus derivatives containing substituted chalcones and substituted chalcone semicarbazones were tested for their antifungal efficacy against Colletotrichum falcatum, Fusarium oxysporum, Curvularia pallescens (all sugarcane pathogens). The O,O-diethylphosphate derivatives containing 2-chlorochalcone and 2-chlorochalcone semicarbazone exhibited 70-85% mycelial inhibition against all the test fungi at 1000 ppm. The screening results were correlated with structural features of the tested compounds.

Abstract:
Abstract Organophosphorus pesticides are currently extensively applied on the control of agricultural and forestry pests. The number of poisonings and deaths caused by organophosphorus pesticides are increasing year by year. Because of the complex matrix, numerous interfering substances, and low poison content, pretreatment methods are crucial for the detection and analysis of such cases. As an adsorbent used for pretreatment, magnetic nanoparticles have the advantages of simple preparation, convenient modification, superparamagnetism, and hydrophilicity. Microextraction can be performed with small amount of magnetic nanoparticles in a short time, and the target substances can be separated with an external magnetic field. In this paper, the latest research achievements are reviewed. Based on the introduced characteristics and preparation methods of magnetic nanoparticles, this paper outlines the applications of different functionalized magnetic nanoparticles for the pretreatment of organophosphorus pesticides and predict the potential research prospects.

Abstract:
This work presents the results of studies of extraction properties in relation to the uranium of bis(2,2,2- trifluoroethyl)diallylamido phosphite, bis(2,2,2-trifluoroethyl)dimethylamido phosphite, and bis(N,Ndialamido)isopropyl phosphite synthesized by us earlier. Tests were carried out in a factory laboratory, as the initial solutions used nitrate solution prepared from uranium oxide (CU = 10.30 g/dm3 , CHNO3 = 56.40 g/dm3 ) and uranium sulfate solution prepared from the chemical concentrate of natural uranium and deoxidized with sulfuric acid (CU = 10.60 g/dm3 , CH2SO4 = 25.10 g/dm3 ). It was proved that the synthesized acyclic amido phosphites can effectively extract uranium from these technological solutions with a proper selection of technological parameters, and the degree of uranium extraction may vary from 34.43 to 95.94%.
