Abstract
Determined are composition, stability and molar quenching coefficient of thorium (4) complexes with bromophenol (BPC)- and bromochlorophenol blue (BCPB) on the basis of spectrophotometric investigations. pH medium being changed, BPC and BCPB behave as acid-base indicators. Within the range of pH values from 1.5 to 5.0 these compounds do not form coloured compounds with alkali and alkaline-earth metal ions, with copper subgroup elements, and also with La/sup 3 +/, Ca/sup 3 +/, Y/sup 3 +/, ZrO/sup 2 +/ and VO/sub 2//sup 2 +/. But interaction of sulfophthaleine with Th/sup 4 +/ is accompanied by change of solution colour. Thus, the investigated sulfophthaleines are specific reagents on Th/sup 4 +/ ions.
