摘 要: | tion resin was studied in hydrochloric acid solution by atomic absorption spectrometry.The results show that gold can be perfectly absorbed by the resin with good selectivity,and the exchange capacity of 1g dry resin is 860 mg Au.the mol ratio between saturated resin and gold was 1.08,except bismuth,other base metals have low absorption ratio,so the resin can be used to concentrate gold from large amount of base metals.The reaction enthalpy was 17.56 kJ/(mol·K).It was shown by the Infra red spectrometry and Raman Instrumentation techniques that gold absorbed in the form of AuCl4-
