摘要
研究了用C410哌啶树脂从氯水溶液中吸附和解吸金的性能。考察了溶液中含金量、搅拌速度和温度对该树脂吸附金的影响。用3％硫脲溶液能够很好解吸金。实验测得该吸附过程的表观活化能值为17.0kJ/mol。对吸附金前后的树脂分别用红外光谱进行了分析比较。
The behaviours of adsorption and desorption of gold from chlorine aqueous solution with new C410 piperidine resin were studied.The effects of gold content in solution, stirring speed and temperature on the adsorption of gold were examined.An apparent activation energy for adsorption of gold was 17.0 kJ/mol. Gold is eluted efficiently with a solution of 3% thiourea.By means of IR-Spectrum,the C410 piperidine resin before adsorbing gold was compared with itself after gold adrorption.
