Abstract Separation of macro amount of gold(III) from a small amount of Pd(II) was investigated by ion exchange. From the screening experiments, a nonionic resin Amberlite XAD7HP was selected for this purpose. The adsorption behavior of Au(III) onto Amberlite XAD7HP followed Langmuir isotherm. The loading capacity obtained from the isotherm agreed well with that experimentally measured. Au(III) solution with 99.99% purity was obtained by eluting the loaded Amberlite XAD7HP with the mixture of HCl and acetone. Comparative studies on the synthesis of gold particles were done from the eluate by adding ascorbic acid and K2CO3 in presence and absence of acetone.

通过离子交换和合成金颗粒从含钯 (II) 的反萃取液中回收金 (III)

摘要 研究了通过离子交换从少量 Pd(II) 中分离大量金 (III) 的方法。从筛选实验中，为此目的选择了非离子树脂 Amberlite XAD7HP。Au(III)在Amberlite XAD7HP上的吸附行为遵循Langmuir等温线。从等温线获得的负载能力与实验测量的一致。通过用 HCl 和丙酮的混合物洗脱负载的 Amberlite XAD7HP，获得纯度为 99.99% 的 Au(III) 溶液。通过在存在和不存在丙酮的情况下添加抗坏血酸和碳酸钾，从洗脱液中对金颗粒的合成进行了比较研究。
