Abstract
|
|
|
|
Resins have been synthesized from chlormethyl styrene 1,4- divinylbenzene(DVB with 1%, 4%. and 20%-crosslinked and macrocyclic ligand of cryptand type by copolymerization method and the adsorption of uranium(VI). nickel( n) and lutetium(Ⅲ) ions have been investigated in various experimental conditions. The correlation between the adsorption characteristics of rare earths and transition metal on the resins and stability constants of complexes with macrocyclic ligand have been examined. The uranium ion was not adsorbed on the resins below pH 2.0. but the power of adsorption of urdnium ion increased rapidly above pH 3.0. The adsorption power was in the order of 1%, 4% and 20%-crosslinked resin. but adsorptive characteristics of resins decreased in proportion to the order of dielectric constants of solvents.
