氨基膦酸羧酸螯合树脂的合成及其对痕量镧系稀土富集分离性能的研究

Synthesis and application of an aminophosphonic-carboxylic acid chelating resin for preconcentration of rare-earth elements

简要叙述了氨基膦酸羧酸树脂的合成路线 ,用 ICP- AES对其富集分离痕量镧系稀土元素进行了研究 ,讨论了吸附酸度、洗脱、吸附流速以及共存离子干扰等的影响 ,并进行了实际样品的分析 ,获得了满意的结果 .

The synthetic method of the aminophosphonic carboxylic acid chelating resin was simply described.Its preconcentration and separation characteristics of the rare earth elements were studied with ICP AES.The influences of sample acidity,desorption,sampling floe rate and the interference of co existing ions were discussed.The proposed method was used to the analysis of a real sample and the result was satisfactory.
