Studies of solvent extraction properties of s-ethyl-N-(diisopropylthiophosphoryl) dithiocarbamate

The results of studying compleXing and solvent extraction properties of thiophosphorylated derivative of dithiocarbamate-S-ethyl-N-(diisopropylthiophosphoryl) dithiocarbomate (TPDTC) and possibilities of its use as analytical reagent are presented. Metal complexes formed by TPDTC are readily extracted by organic solvents. The study of complex extraction by chloroform solution of the reagent versus the medium acidity has shown that the Hg-(2), Ag-, Bi-. Sn-(2), Cu(2) complexes are quantitatively extracted from acid media. Co-(2), Ni-, Cd-, Zn-, Pb(2) complexes are extractable from weakly acid and neutral solutions. Such elements as Fe, Mn, As, Cr, Sb are not extractable from either acid or neutral media
