Abstract
Modified polymer matrices based on methacrylic acid (MA) cross-linked with triethylene glycol dimethacrylate (TGM-3) or divinylbenzene (DVB) were synthesized. Diethyl allylphosphonate (DEAP), dibutyl allylphosphonate (DBAP), and diethyl vinylphosphonate (DEVP) were synthesized and used as matrix modifiers. To obtain sorbents based on the matrices prepared, two methods of introducing the extractant, tetraoctyldiglycolamide (TODGA), were chosen: impregnation and in situ method. The second method proved to be worse because of lower mobility of the extractants inside the matrix. In addition, the kinetics of f-element cation sorption also correlated with the water sorption rate. The presence of active binding sites on the surface of the polymer matrix affects the complexation of the Eu(III) ion, but the extractant applied to its surface makes the major contribution to the sorption of the ions under study.
