In this study,a method for simultaneous determination of lead and total arsenic in drinking water by using atomic fluorescence spectroscopy was established.The results showed that the optimal conditions were obtained with a K3[Fe(CN)6]concentration of 1.00%,a KBH4 concentration of 1.50%and a thiourea concentration of 1.00%.The linear range was good at 0~10 μg·L-1 for both lead and arsenic,and the detection limits were 0.10 μg·L-1 and 0.15 μg·L-1,respectively.The recovery values were 98.4%~103.3%.The proposed method saves cost,improves the detection efficiency,and is suitable for popularization and application.
