摘　　要：本文阐述了用MP—1型溶出分析仪对紫苏色素中铅、汞、砷的测定．其中铅和汞分别以玻碳汞膜电极和玻碳预镀金膜电极为工作电极，微分电位溶出法测定；砷以示波极谱法测定．我们对方法的精密度、线性关系进行了实验验证，结果表明本法简单、快速、灵敏，获得的结果较好．The Ph in perilla pigment was determinated by DPSA with a thin film of mercury on a glass carbon electrode. and the Hg with a thin film of gold film on a glass carbon electrode. The As was determinated by polargraphic analysis. The precision and accuracy had been studied. The results showed that this method was simple, high speed, sensitive and reliable.
