摘　　要：文章采用络合滴定法测定和原子吸收光谱法测定皮蛋中铅的含量,结果表明:络合滴定法测定法过程简单易行,结果重现性强,准确度高,适用于铅含量相对较高的皮蛋中铅的测定。而原子吸收光谱法灵敏度高,可以检出皮蛋中少量的铅含量。市面上散装的皮蛋铅含量远超国家安全标准。Lead content in preserved egg was measured by using compleximetry and atomic adsorption spectrometry. The results show that compleximetry is simple, accurate, reliable and reproducible. It is sutiable for the determination of lead with high concentration in preserved egg, while atomic absorption spectrometry is sensitive enough to detect the presence of low content lead in preserved egg. Lead content in bulk preserved egg which bought from vegetable market is beyond the national standard.
