用氢氧化钠提高泡塑富集金能力的探讨

Study on raising concentration capacity of gold by using sodium hydroxide

研究了用氢氧化钠处理的泡塑在分离富集金过程中金的回收率，吸附范围及金在分析过程中的分布情况。研究表明用氢氧化钠处理的泡塑回收率高，富集能力强，并据金的分布情况对影响泡塑富集能力的原因进行了探讨，为泡塑分离富集金的分析提供了一种新的泡塑预处理方法。

The gold recovery rate in the course of concentration and separation by sodium hydroxidetreated foam plastics,the range of adsorption and the gold distribution in the course of assay are studied.It shows from study that the gold concentration capacity is great and the gold recovery rate is high through the application of sodium hydroxidetreated foam plastics.The study of the effect of gold distribution on concentration capacity of foam plastics is also made which provides a new method to pretreat foam plastics for gold concentration and separation.
