Opis:: The novel broom methylcarbamoylmethoxy-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).

Opis:: A novel tripodal thioester type of broom extractant has been synthesized to investigate selectivity for soft metal ions. Broom extractant exhibited high extractability for silver ion compared with monopodal compound. The complexation ratio of the broom extractant and silver ion was found to be 1:1 from the result of extractant concentration dependency. For stripping of loaded silver ion, complete stripping was achieved with both 1 mol dm-3 thiourea and high concentration of acidic solutions. As an application, electrode response of silver ion was observed at concentration range of 10-3 to 10-6 M silver nitrate using broom extractant as an ionophore.
