Abstract
Trace amount of antimony (0.45∼0.28 μg/ml) has been determined by sub- and super-equivalence method in isotope dilution analysis. Substoichiometric amount of Sb(III) was oxidized to Sb(V) by potassium dichromate and separated by BPHA (in CHCl3) extraction. It has been found that the determination can be performed within an accuracy of 2% in the wide region of acid concentration.This publication has 2 references indexed in Scilit:
