本文系统研究了泡沫塑料动态快速分离富集金的方法。对泡沫塑料柱的处理方法,再生及主要共存离子干扰的消除等均做了较详细的研究。提出了一种简便,不控速的金分离富集的方法。该法用于分析0.051～3.59g/t四种不同含量的金标样,结果与推荐值吻合,5次分析结果,相对标准偏差<5％,同时,可用泡沫塑料柱当天连续使用分析拿标样,回收率为93％—109％。
This article systematically studied the rapid and dynamic method of foam separation and enrichment of gold. The treatment method of foam column, regeneration and the elimination of the main co-existing ion interference were all studied in detail. A simple and uncontrolled gold separation and enrichment method was proposed. The method was used to analyze gold standard samples of 0.051 ~ 3.59g / t in four different contents. The results were consistent with the recommended values. The results of five times analysis showed that the relative standard deviation was less than 5%. Meanwhile, Like, the recovery rate of 93% -109%.
