Abstract
The work reported in this manuscript deals with the synthesis of phosphonic monomers and polymers, together with the characterization of their complexing properties for selected lanthanides (Ln) and actinides (Ac). The poly(diethyl-6-(acrylamido) hexylcarbamoylmethylphosphonate) (P(CPAAm6C)) and its mono-hydrolysed derivative mhP(CPAAm6C), which contained carbamoylmethylphosphonate groups, were first evaluated for the sorption of gadolinium (Gd(III)) and thorium (Th(IV)), using analytical and calorimetric (ITC) tools. Then, a new monomer oxymethylphosphonate (DiAPC1) was synthesized and polymerized. Polymers before and after hydrolysis, poly((acryloyloxymethyl) phosphonic acid) (hP(APC1)), were evaluated with cerium (Ce(III)) and neodymium (Nd(III)). Finally, another monomer containing acrylamide polymerizable group and phosphonate, named diethyl-2-(acrylamido)ethylphosphonate (DAAmEP), was used to obtain P(DAAmEP) and then hydrolysed leading to hP(DAAMEP). Both polymers were finally evaluated with gadolinium (Gd(III)), cerium (Ce(III)), neodymium (Nd(III)), and thorium (Th(IV)).
