| 摘 要： | 研究了用配位滴定法连续测定铅、锌含量的方法。对铅锌离子混合溶液,采用在pH值5~6的缓冲体系中,以邻二氮菲掩蔽锌离子,用EDTA标准溶液单独测定铅,获得了较好的准确度,减少了锰、钴、铜、镍等离子的干扰;然后在不加掩蔽剂条件下测定出铅锌总量从而计算出锌含量。该法实现了对铅锌混合离子的快速准确测定,可用于铅锌矿中铅锌的测定。

| Abstract: | This paper discusses the measurement of the content of Zinc simultaneously by complex formation titration of Zinc and lead. In the buffer solution with the pH of 5-6, the total amount of the zinc （II） and lead（II） was titrated. Then the lead（II） was titrated by masking zinc （II） with phenanthroline.This method can continuously titrate zinc（II）/lead（II） in lead zinc mine. |
