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 ,有一定的实用性 The method for simultaneous determination of zinc content by zinc and rare earth element simultaneous titration was discussed. Under appropriate conditions, the total amount of mixed or single rare earth (III) and zinc (II) is titrated with EDTA and the amount of rare earth (III) titrated with zinc after masking in another solution. The difference between two titrations Find the zinc content, the result is ideal. The method is simple, rapid, and has some practicality
