Hasany, S. M. published the artcileExtraction and separation of mercury from toxic elements arsenic, cadmium, antimony and thallium, and other metal ions, Computed Properties of 1691-93-6, the main research area is mercury extraction toxic element; arsenic mercury separation; cadmium mercury separation; antimony mercury separation; thallium mercury separation.
Extraction of Hg with 3-methyl-1-phenyl-4-trifluoroacetylpyrazolin-5-one in CHCl3 is described. Maximum extraction (97.3%) and a distribution coefficient (D) of 36.5 are achieved at pH 8. Among the anions tested, thiourea, thiosulfate, and cyanide mask the extraction of Hg. A solution of 0.2M KCN was the most suitable stripping agent for Hg. Decontamination data show that Hg can be separated from toxic elements As, Cd, Sb, and Tl and from other metal ions, i.e., Ga, In, Ge, Sn, Fe Ir, and Pt. A few separations of anal. and radiochem. importance are discussed.
Journal of Radioanalytical and Nuclear Chemistry published new progress about Toxicants. 1691-93-6 belongs to class pyrazoles-derivatives, name is 5-Methyl-2-phenyl-4-(2,2,2-trifluoroacetyl)-1H-pyrazol-3(2H)-one, and the molecular formula is C12H9F3N2O2, Computed Properties of 1691-93-6.
