从吸附平衡和吸附动力学观点,研究了TBP浸渍树脂在HCl分质中对金的分配比。用原子吸收法测定了TBP浸渍树脂对AuCl_4~-的吸附速率和等温吸附线。根据吸附平衡的研究,树脂对AuCl_4~-的反应机理为: 3TBP+H_3~+O+AuCl_4~-(TBP)_3H_3~+O·AuCl_4~-
From the viewpoint of adsorption equilibrium and adsorption kinetics, the distribution ratio of gold to TBP impregnated resin in HCl was studied. The adsorption rate and adsorption isotherm of AuCl_4 ~ - with TBP impregnated resin were measured by atomic absorption spectrometry. According to the study of adsorption equilibrium, the reaction mechanism of resin to AuCl 4 ~ - is as follows: 3TBP + H_3 ~ + O + AuCl_4 ~ - (TBP) _3H_3 ~ + O · AuCl_4 ~
