Abstract

The determination of the content of iron and copper in the sulfuric acid by FAAS is described in this paper.Six different kinds of surfactants' effect were investigated,0.2%(mass fraction)Tween-80 is chosen as synergist.The results show that:RSD of the determining is 0.41%~5.52%;Fe:the detection limit 0.008 6 μg/mL,the sensitivity 3.19 μg/mL;Cu:the detection limit 0.019 4 μg/mL,the sensitivity 5.36 μg/mL; the recovery between 97.3%~100.3%.
