| 摘 要： | 基于二苄基硫醚树脂与钯的络合反应,建立了一种高选择性固相萃取吸附钯的方法。在0.1~6.0 mol/L的HCl介质中,钯可以被二苄基硫醚树脂吸附富集并形成1∶2稳定络合物,该络合物可用20 g/L酸性硫脲溶液洗脱,洗脱液经处理后用分光光度法测定,树脂结构不被破坏且可重新处理使用。方法用于吸附分离钯,回收率达90%以上。

| Abstract: | On the basis of the complex reaction of dibenzyl sulfide resin with palladium, a high selective method of solid phase extraction for the adsorption of palladium was developed. In 0.1～6.0 mol/L HCl media, palladium could be adsorbed and enriched by dibenzyl sulfoxide resin and a stable complex with ratio of 1∶2 was formed. The complex could be eluted by 20 g/L acidic thiourea, and the eluent was determined by the spectrophotometry. The structure of resin was kept well, which could be retreated and reused readily. The method has good selectivity for adsorption of palladium in the acidic system containing palladium, and the recovery is above 90%. |
