【摘要】 SG树脂是我们合成的以交联聚苯乙烯为骨架,以胍基为功能团的新型树脂。本文针对矿样分析及柱色谱分析的要求,进行了淋洗液选择、淋洗速度、上柱流速、王水浓度及干扰离子影响等条件实验。并作了模拟金矿的合成样及四种金矿的测定,得到满意的分析结果。更多还原

【Abstract】 A new type of SG chelating resin containing quanidine as functional group was synthesized. Several optimum conditions for concentrating and separating gold from base metal by SG resin column chromatography were investigated. Golb can be absorbed by SG resin in a wide range of 0. 1～6 mol/L HCl and separated from base metal in lmol/L HCl. A solution of 90% actone-5% HC1一5%H₂O was chosen as the best elucnt for Au（Ⅲ）. Several gold ores were analyzed with good results.更多还原
