摘要
C411树脂在盐酸或王水酸性介质中能很好地吸附金,金矿中常见元素不影响金的吸附。吸附后的金用硫脲溶液洗脱较完全和容易。本文研究了C411树脂在酸性介质中吸附和解吸金的性能,并与410哌啶树脂进行了比较。
Gold can be adsorbed selectively in the medium of HCL or aqua regia by C411 ion-exchange resin, There is little or no interference usually from coexisting metal ions in gold ore. Gold adsorbed on the resin is easy and fully to be eluted with a solution of thiourea, The gold adsorption and elution properties of C411 ion-exchange resin in acid medium are studied and a comparison between C411 resin and 410 piperidine resin is made in this paper
