| 摘 要： | 研究了用锌、稀土元素的同时配位滴定法测定锌含量的方法。在pH=5—6的缓冲溶液中，用EDTA标准溶液测定混合或单一稀土（Ⅲ）和锌（Ⅱ）的总量；然后在另一份溶液中用1，10-邻菲啰啉溶液把锌掩蔽后用EDTA标准溶液测定稀土（Ⅲ）的含量，再由稀土（Ⅲ）和锌（Ⅱ）的总量减去稀土（Ⅲ）的含量而求得锌的含量。该方法操作简便、迅速，有较大的实用性。

| Abstract: | This paper discusses the measurement of the content of Zinc simultaneously by complex formation titration of Zinc and spare soil.In the buffer solution with the pH of 5~6,we titrate the total amount of the mixed or single sparse soil(III) and Zinc(II) with EDTA buffer solution,the content is marked as A; and in another portion,after masking Zinc(II) with a kind of masker,we titrate the amount of spare soil with EDTA solution,marking the result as B;next,the value of A minus B is the content of Zinc.The speed of this method is very fast.Moreover,it is very simple to operate and much practical. |
