共沉淀现象为人们提供了一个简单有效地富集微量元素的好方法,特别是随着生产和科学技术的发展对材料纯度的要求日益提高,共沉淀富集也就更加受到分析化学工作者的重视。本文仅就共沉淀富集的机理和应用的情况作一概括的介绍,供分析工作者参考。一、共沉淀的分类与机理从共沉淀载体来看,可分为无机共沉淀剂和有机共沉淀剂两大类。它们的作用机理是大不相同的。
Coprecipitation provides a simple and effective method for enriching trace elements. Especially with the increasing demand for the purity of materials due to the development of production and science and technology, coprecipitation enrichment is also more influenced by the analytical chemistry workers Pay attention. This article only on the coprecipitation enrichment mechanism and application of a general introduction for the analysis of workers reference. First, the coprecipitation classification and mechanism From the co-precipitation carrier point of view, can be divided into inorganic coprecipitant and coprecipitant two categories. Their mechanism of action is very different.
