摘要
对甲醛法测定铵根含量的方法进行了研究,建立以EDTA-Ca为掩蔽剂,消除重金属离子的干扰,采用酸碱滴定的甲醛法测定有大量重金属离子存在的锌电解液中的铵根含量的方法,为监测具体生产情况提供可靠保证。
The determination of ammonium content by formaldehyde method was studied, and the method was established for the determination of ammonium content in zinc electrolytic with a large number of heavy metal ions by acid-base titration using EDTA-Ca as masking agent to eliminate the interference of heavy metal ions. Provide a reliable guarantee for monitoring specific production conditions.
