摘要： 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NH4SCN解吸动力学作了系统的考察。

Abstract: In this paper, we have studied the adsorption properties of gold by BPRin alkali solution, the single and dual component kinetic mass transfer process of Au(I), Ag(I) and other metal cyanide ions.The results obtained show that the mass transfer rates of the cyanide ions in the resin phase are closely related to the molar ratio and the configuration of metal cyanide ions.The elution kinetics of Au(I) and other cyanide ions by NH4SCN has been investigated systematically.

Key words: BPR resin, Gold, Adsorption and elution kinetics
