本文采用阳离子树脂分离干扰元素，再用ＰＭＢＰ─苯萃取稀土，３％ＨＣｌ反革稀土，采用ＣＰＡ－ＰＮ显色，络合物最大吸收波长６８０１ｎｍ，ε６８０＝５．０３×１０４：稀土浓度在０－２５μｇ－１范围内符合比尔定律。
In this paper, the cationic resin was used to separate the interference elements, and then PMBP-benzene was used to extract the rare earth and 3% HCl counter-ternary rare earth. CPA-PN was used to develop the complex. The maximum absorption wavelength of the complex was 6801 nm and ε680 was 5.03 × 104. Beer’s law is valid in the range of -25μg-1.
