| 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 0.0086μg/mL,the sensitivity 3.19μg/mL;Cu：the detection limit 0.0194μg/mL,the sensitivity 5.36μg/mL; the recovery between 97.3%-100.3%. |
