摘要
探讨了用锌、稀土元素的同时配位滴定法测定锌含量的方法。在适当的条件下 ,用EDTA滴定混合或单个稀土 (Ⅲ )和锌 (Ⅱ )的总量 ,在另一份溶液中把锌掩蔽后滴定稀土 (Ⅲ )的量 ,由两次滴定的差值求得锌的含量 ,结果理想。该法操作简便、迅速 。
Discusses the measurement of the content of zinc by using simultaneous coordinate titration of zinc and rare-earth element .Under appropriate condition,titrated the total amount of the mixed or single rare-earth element(Ⅲ)and zinc(Ⅱ)with EDTA and the amount of rare-earth element after the zinc was masked in another solution,and get perfect results.
