测定了HW型吸附树脂对模拟氰化液中Au(Ⅰ)的静态吸附能力,研究影响吸附的一些因素。结果表明,HW树脂在中性条件下对Au(Ⅰ)的吸附量与活性炭接近,碱性条件下吸附量降低较多。某些胺的存在可使树脂吸金量提高十倍。树脂的解吸性能良好,解吸效率接近1o0％。
The static adsorption capacity of HW-type adsorption resin to simulated Au (I) in simulated cyanide solution was determined and some factors affecting the adsorption were studied. The results showed that the adsorption capacity of HW resin to Au (Ⅰ) was close to that of activated carbon under neutral condition, while the adsorption capacity of Al (Ⅰ) decreased more under alkaline condition. The presence of certain amines can increase the amount of resin absorbed by ten times. Desorption of resin is good, desorption efficiency close to 1o0%.
