摘要
本文提出了具有双功能基的丙二酰胺新型树脂的合成,研究了它吸附贵金属金、铂、钯的速度及酸度影响,以及它对其它贵金属和非贵金属的吸着情况,重点在于考察常见非贵金属对金测定的影响。并用于矿石中金的测定,结果与参考值一致。经红外光谱研究,树脂吸附金的机理是质子化了的丙二酰胺树脂与AuCl_4^-生成离子对的离子缔合反应。
We are the first to synthesize a new propanediamide resin and to study its sorption behavior and application to noble metals. It was found that in dilute hydrochloric acid medium Au.Pt.Pd were completely sorbed by this resin but most of the non- noble metals were not. This resin has a high selectivity for Au. By infrared absorption spectrum , the possible sorption mechanism of ion association was suggested. Au in ores was concentrated with this resin and then analyzed with satisfactory results.
