摘要
在一定的条件下,对氯偶氮氯膦(CPA_pC)与等量的15种单一稀土所形成的络合物具有彼此相似的吸光度值。且该试剂也是钪的灵敏显色剂。据此分析特性,连续测定了矿石中稀土总量与钪,分析结果与标准数据基本相符。
Under the certain experimental conditions, the complexes formed in the reactions of CPApCwith 15 rare earths have approximate absorbance values. Additionally, CPApC is also a sensitivechromogenic reagent of scandium. Based on these analytical characteristics, a new method for thesuccessive determination of total rare earths and scandium with CPApC was developed. This me-thod has been applied to the ores analysis. The results are coincident with the standard data.
