摘要
介绍了钙锌盐中锌含量的测定,重点围绕钙锌盐中的Fe、Al等金属离子的存在下,如何消除干扰后,采用EDTA络合滴定法准确的测定锌的含量。
This paper introduces the determination of the zinc content in calcium-zinc salt. It focuses on how to eliminate the interference when Fe, Al and other metal ions exist in the calcium-zinc salt. EDTA complexometric titration is applied to accurately determine the zinc content.
