解毒渣中水溶性总盐的测定

Determination of water soluble total salt in detoxification residue

解毒渣的水溶性总盐是解毒渣分析的一项比较重要的指标。盐浓度的增大,沉淀的盐效应也增大,即沉淀的溶解度增加,盐浓度高会诱发重金属的释放,不利于环境保护。本文详细介绍了解毒渣中总盐测定的推荐方法,方法的准确度和精密度较好,步骤操作简单。

Water soluble total salt of detoxification residue is an important index in detoxification residue analysis.With the increase of salt concentration,the salt effect of precipitation also increases,that is,the solubility of precipitation increases.High salt concentration will induce the release of heavy metals,which is not conducive to environmental protection.In this paper,the recommended method for the determination of total salt in detoxification residue is introduced in detail.
