Abstract
A new method is developed for the rapid extraction and direct photometric determination of antimony. With 20% TBP-toluene 3 to 15 μg of antimony is extracted from 2m hydrochloric acid containing 1 m magnesium chloride. From the organic phase, antimony is directly determined photometrically at 640 nm as its complex with brilliant green. Antimony can be selectively extracted in the presence of a large number of cations and anions. The total operation requires only 20 min.This publication has 13 references indexed in Scilit:
