考察了BPR树脂在碱性条件下对金的吸附性能。研究了BPR提取Au(Ⅰ)、Ag(Ⅰ)及其它金属氰合离子的单、双组分动力学传质过程。结果表明,树脂相上氰合离子的传质速率和摩尔比与其结构类型有密切的关系,对Au(Ⅰ)等氰合离子的NH_4SCN解吸动力学作了系统的考察。
The adsorption properties of BPR resin to gold under alkaline conditions were investigated. Single and double component kinetic mass transfer of Au (Ⅰ), Ag (Ⅰ) and other metal cyanide ions by BPR were studied. The results show that the mass transfer rate and molar ratio of cyanide ions on the resin phase are closely related to their structure types, and the desorption kinetics of NH_4SCN for cyanide ions such as Au (Ⅰ) is systematically investigated.
