Polymeric matrices composed of glycidyl methacrylate/divinylbenzene and glycidyl methacrylate/N,N′-methylenebis(acrylamide) were prepared concurrently in the presence of dispersed fine magnetite particles. The obtained products were allowed to react with tetraethylenepentamine to produce two amino-magnetic resins named RI and RII. The adsorption of Th(IV) ions on RI and RII from nitric acid solutions...
Glycidyl methacrylate chelating resins were obtained through copolymerization of glycidyl methacrylate (GMA) with divinylbenzene (DVB) in the absence and presence of magnetite particles to give GMA/DVB (RI) and GMA/DVB-magnetite (RI-mag), respectively. RI and RI-mag resins were treated with tetraethylenepentamine to give RIa and RIa-mag resins. The uptake behavior of RIa and RIa-mag towards U(VI)...
