| Abstract: | Trace amounts of rare earth(RE)elements,including La,Nd,Eu,Gd,Er and Yb in water sample were adsorbed and enriched by weak acid cation exchange fiber column,and desorbed from the column by eluting with 1.0 mol/L HCl.The solution obtained was used for ICP-AES analysis.Under the optimum conditions,the adsorption capacity of weak acid cation exchange fiber column toward La,Nd,Eu,Gd,Er and Yb were found to be 86.5,98.2,98.7,99.2,84.9,91.5 mg/g.The values of detection limits(3S/N)of this method for La,Nd,Eu,Gd,E... |
