本文首次研究自制的氨基胍基螫合树脂吸附贵金属的行为。测定了树脂在HCl及H_2SO_4介质吸附贵金属的分配系数和吸附百分率,并研究了各种贵金属的吸附速率、以及酸度和温度等对吸附过程的影响。并提出树脂对贵金属配阴离子的配位和交换共存的吸附历程。
This is the first study of the adsorption behavior of home-made aminoguanidine resins on precious metals. The partition coefficient and adsorption percentage of resin adsorbed on the noble metal in HCl and H 2 SO 4 media were measured. The adsorption rates of various noble metals, the effects of acidity and temperature on the adsorption process were also studied. The adsorption process of coordination and exchanging of resin with noble metal anions was proposed.
