摘要
该研究用钍试刺工与D290大孔强碱性阴离子树脂螯合形成树脂分离、富集岩石样品中的贵金属铑，用火焰原子吸收分光光度法测定。实验表明，在pH=1．0条件下，铑定量上柱，用1mol／L的HCl洗脱，火焰原子吸收分光光度计直接测定，回收率在96％～103％，相对标准偏差＜3％。
The research aims at identifying the content of Rh in rock samples by using the flame atomic absorption spectrometry （FAAS） with the help of applying Thorin Ⅰ and D290 （the macroporous basic anion） chelate-formlng resin to separate matrix elements and concentrate rhodium from the samples. The experiment shows that Rh passes through columns when pH is 1.0, with 1 mol/L HCI as elution solution, then, measured by FAAS, the content of Rh can be determined. The recovery ratio of Rh ranges from 96% to 103%, the relative standard deviation is less than 3 %.
