主要报道了用金橙G螯合负载形成树脂分离富集地质样品中贵金属Rh的方法。在最佳试验条件下Rh的回收率可达95%~105%之间;其相对标准偏差为4.49%;百分相对误差较小,为-2.4%;方法无系统误差;用硫脲洗脱,该负载形成树脂不被破坏,重复使用5次,树脂均未见异常,均能定量回收,回收率在98.5%~104%之间,符合要求。说明,这种负载形成树脂也较稳定,也可用于实际地质样品中微量贵金属的分离富集
This paper mainly reports the method of separating and enriching precious metal Rh in geological samples by gold chelated orange G chelating resin. Under the optimal experimental conditions, the recovery rate of Rh can reach 95% -105%, the relative standard deviation is 4.49%, the relative percentage error is small, which is -2.4%; the method has no systematic error; Thiourea elution, the load-forming resin is not damaged, repeated use of 5 times, the resin were not abnormal, can be quantitative recovery, the recovery rate of 98.5% to 104%, in line with the requirements. This shows that this load-forming resin is also relatively stable and can also be used for the separation and enrichment of trace precious metals in actual geological samples
