作者测定了聚三烯丙基氰尿酸酯(PTAC)树脂的孔结构及对Au(Ⅲ)的吸附性。包括pH值、初始金液浓度,共存金属离子存在下对金的吸附.实验结果表明,(PTAC)大孔吸附树脂对Au(Ⅲ)的吸附是通过分子链上氮或氧原子的孤电子对与H_3~+AuCl_4~-离子对形成弱键。
The authors measured the pore structure of poly (triallyl cyanurate) (PTAC) resin and its adsorptivity to Au (Ⅲ). Including the pH value, the initial concentration of gold liquid and the adsorption of gold in the presence of coexisting metal ions.The experimental results show that the adsorption of Au (Ⅲ) by (PTAC) macroporous adsorption resin is through the lone pair of nitrogen or oxygen atoms in the molecular chain Weak bond with H_3 ~ + AuCl_4 ~ - ion pair.
