Description
The novel broom methylcarbamoyl methoxy-acetic acid impregnated resin has been prepared to investigate the adsorption behavior of nine rare earth metals. The present resin demonstrates adsorption ability for rare earth metal ions. The selectivity order for rare earth series is as follows: Ho>Er>Gd>Y>Eu>Sm>>Nd>Pr>>La. This order is different from those of general carboxylic acid extractants. Maximum adsorption capacity of holmium is found to be 0.21 mol·kg-1.From the comparison of the reagent amount impregnated in the resin and the maximum adsorption capacity, the adsorption stoichiometry is found to be 1:2 (Ho:reagent).
