A simple method based on hydride generation(HG)-AFS for the determination of As in lead-based alloys was developed.Interferences caused by co-existing elements were investigated and minimized successfully.The conditions for the hydride generation technique and instrumental parameters were also optimized.KBH4 concentration was fixed in 1.0%(m/V).Optimized HCl concentration in the sample and carrier solution was 10%(V/V) and 5%(V/V),respectively.Experiments showed that no interference caused by Cu was observed when thiourea existed and interferences caused by Sb,Sn and Bi could be eliminated by absorbing their corresponding hydrides using 0.5%(m/V) KMnO4 solution on-line.Feasibility of this method was demonstrated by determination of two certified lead-based alloys,and the results obtained by standard addition agreed well with certified values.The method detection limit was 0.17 μg/L and RSD was 1.5% for 11 consecutive determinations of 40 μg/L As standard solution.
