Екстракційно-фотометричне визначення деяких важких металів в об’єктах довкілля

Abstract

A possibility of extractive-photometric determination summary contents same heavy metals (Hg, Cd, Pb) and separate determination of mercury(II) in objects of environments with new reagents 3-phenyl-5-thiooxo-4-alyl-4,5-dihydro-1H-1,2,4-thriazol-1-carbodithionat sodium and cyanine dye of chloride 1,3,3-thrimethyl-2-[(E)-3-(1,3,3-thrimethyl-2,3-dihydro-1H-2-indoliniliden)-1-propenyl]-3Hindoliy is has showed. A procedure of extraction-photometric determination of heavy metals in waters and soils has developed.
