| 摘 要： | 研究了盐酸浓度、氯化钠浓度、金和钯的起始浓度、选择性络合剂及温度等因素对Ｐ－９５０树脂分离金和钯的影响．结果表明，在适宜的盐酸浓度和有氯离子存在的条件下，该树脂能优先吸附金．提高温度有利于金与钯分离．用有机醛、酮为络合剂（ＲＯ）可从载有金和钯的树脂上选择性解吸金，而钯不被解吸，从而达到金和钯分离的目的

| Abstract: | The effect of concentration of HCl and NaCl, initial concertration of gold and palladium, selective legand and temperature on the separation of gold and palladim with P-950 piperidine resin was investigated.Experimental results showed that gold was adsorped first by the resin at suitable concentrations of HCl and NaCl. The separation was improved with the increase of temperature. Gold was desorped from the resin by selective legand RO, but palladium remained in the resin under the same condition. Thus separation of gold and palladium by these methods is feasible. |
