摘要
本文报道了D—290大孔强碱性阴离子交换树脂吸附金的机理、酸度曲线、吸附速率、平衡时吸附的容量及吸附反应活化能。通过柱色谱试验,拟定了用D—290树脂分离、原子吸收法测定阳极泥中微量金的方法,取得较好结果。
This paper reported the mechanism of gold adsorption by D-200 macroporous basic anion exchange resin, including the acidity curve, the adsorption velocity, the adsorption capacity when in equilibrium and the-activated energy of adsorption reaction. Through column chromatograpbic test, a programme for the separation of trace gold in anode mud by using D-290 resin and the determination of trace gold by using the method of flame atomic absorption was put forward bringing about a better result
