| Abstract: | 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. |
