摘要
研究了以亚铁氰化钾为还原剂铅在铂电极上的还原电位溶出法；讨论了电极的预处理、阳极富集和随后的还原电位溶出及铅测定的干扰。
The reductive stripping potentiometric analysis of lead in the presence of potassi-um ferrocyanide as reducing agent on platinum electrode has been investigated. The pretreat-ment of the electrode, processes of anodic preconcentration and subsquent analysis,and theinterference of foreign ions were discussed.The linear range was 1× 10-7to 5 × 10-6mol/Lfor lead.
