摘　　要：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％。A systematic study for high-speed dynamic separation and preconcentration of gold with polyurethane foam has been described. We have given a detailed study to the method of handling polyrurethane foam, service life of polyurethane foam,and serious interference etc.and presented a new and high-speed,simple and convenient method. The procedure has been applied to the separation and determination of gold in several geological standard samples with gold contents in a range of 0. 051 -3. 59g/t. The relative error of determination is less than 10% and polyurethane foam was continuously used for the determination of the geological standard sample with satisfactory results.The recovery is 93%-109%.
