【摘要】 研究了仲碳伯胺（N1923）萃淋树脂吸萃金的机理，溶液酸效应、吸附等温线、吸附速率、盐析剂效应及柱操作条件的影响等，将该树脂用于矿样中金含量的测定，结果与717＃离子交换树脂吸附法一致，取得了较好的结果。更多还原

【Abstract】 The property and mechanism of adsorptive extraction of gold with levextrel resin N1923 were studied under different conditions. Results shows that N1923 resin is a new selective stationary phase for gold. It was found that gold could be retained on N1923 resin column in 0. 5 mol/L HCl. The eluant of gold is 2% thiorea solution or 1% sodium sulfite solution.The recovery of gold in the determination of ore sample is almost the same as that with ion exchange resin 717 #.更多还原
