Abstract

atomic fluorescence spectrometry was applied to the determination of antimony in water.The water sample was pretreated by 5% hydrochloric acid and 5% Thiourea-5% Ascorbic acid.The determination of antimony in water is based on 2% potassium borohydride and 0.5% potassium hydroxide taken as reducer in medium of 5% hydrochloric acid.The detection limits is 0.2 μg/L.This method has a better correlation coefficients(r0.999) and higher precisions.The recovery rates ranges from 99.5% to 101.5%.This method is simple,high sensitive and has less interference.It is suitable to determine antimony in water.
