Abstract

Method for extraction-photometric determination of chromium (III) that includes formation and extraction with toluene of dyed ion associate with organic reagents with following photometering, at that as organic reagents one uses sodium salt of 1-naphthoylhydrazone of pyruvic acid and cyanine dye astraphloxin FF, and extraction with toluene of ion associates of chromium (III) is carried out at pH 5,7-7,8 with level of extraction - 88,7 %.
