Abstract: In this dissertation , the lead content was determinned hydride atomic fluorescence spectrometry .,we explored the Pb fluorescence intensity influential factors such as currentcarrying acidity , acidity of solution , concerntration of red potassium prussiate,concerntration of reducer , and proposed the optimal experiment condition .Then recovery ,precision accuracy experiments have been investigated , also the sample have been analyzed under the optimal experiment condition , the detection limit is 0.0031μg/L , the correlation coefficient is 0.9921 , standard deviation is less than 10% , the coefficient of recovery is between 81.7%—88.0% . Hydride atomic fluorescence spectrometry has some advantages when determined the lead content such as good correlation coefficient , high sensitivity , exact result , low cost and easily to handle , also it is wide prospect.
