Abstract:
0.999). The characteristic masses and detection limits achieved were as follows,as for As,21 pg and 0.13 ?g/L,as for Se,32 pg and 0.33 ?g/L. The recoveries were 96.0%-103.6% for As,98.3%-104.7% for Se and the RSDs were 0.6%-1.7% for As,0.6%-2.8% for Se. Conclusion This method was accurate, simple and sensitive,it is applicable to the determination of trace As and Se in water.
