中文摘要：

实验研究了D296型强碱性阴离子交换树脂对硫代硫酸根络合金阴离子（[Au（S_2O_3）_2]~（3-））的吸附及洗脱过程。在常温常压下,考察了吸附溶液的pH值、铜氨浓度、亚硫酸盐浓度、硫代硫酸盐浓度以及树脂用量、搅拌速度等对吸附过程的影响。载金树脂的金洗脱实验表明,直接用硫脲加盐酸洗脱为宜。

英文摘要：

Adsorption and elution of gold-thiosulfate complex anion by D296-type strong alkali anion exchange resin was investigated. The experimental conditions, such as pH value, concentration of copper ammonia, sodium sulfite, and sodium thiosulfate, amounts of resin and stirring speed, were tested at ambient temperature and pressure. Experimental results of elution showed that gold adsorbed on resin could be directly eluted by mixture of thiourea and hydrochloric acid.
