应用AmberlystA-26大孔阴离子交换树脂分离金(III)、钯(II),并分别用有机试剂N-烯丙基-N’-(安替比林基)硫脲(AATu)和N-间甲苯基-N’-(氨基对苯磺酸钠)硫脲(MMPT)在最佳显色条件下进行测定。用于试样分析,回收率分别为Au:93.4%～95.2%,Pd:96.3%～98.6%。
The gold (III) and palladium (II) were separated by Amberlyst A-26 macroporous anion exchange resin and separated with organic reagent N-allyl-N’- Tolyl-N ’- (sodium p-aminobenzenesulfonate) thiourea (MMPT) was determined under the optimal conditions for color development. For sample analysis, the recoveries were Au: 93.4% ~ 95.2%, Pd: 96.3% ~ 98.6%.
