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 certain conditions, the complexes formed by chloropalladine chlorophosphonazo (CPA_pC) with an equivalent amount of 15 single rare earths have absorbance values similar to each other. This reagent is also a sensitive scandium developer. Based on this analysis of properties, continuous determination of the total amount of rare earth ore and scandium, the analytical results and the standard data are basically consistent.
