Polymeric nanoparticles of poly(methyl methacrylate)were obtained by emulsion polymerization techniques in a process of two stages.The particles were functionalized with acrylic acid,curcumin,and fumaramide and three series of polymeric particles were obtained.The incorporation of functional groups was confirmed by Fourier transform-infrared spectrosocopy(FT-IR)and ultraviolet-visible(UV-Vis)methods.The spherical morphology of particles with an average diameter of 100 nm was observed by scanning electron microscopy(SEM).The polymeric materials were used for recovery of[Eu]from synthetic solutions.The nanoparticles show excellent chelation capacity to trap rare-earth ions,because they recover more than 85％of[Eu]at pH of 2.The images of SEM after extraction process show arrays between particles with larger average particle sizes to 1.5 μm.In addition,the particles have a good stripping capacity,exceeding 50％of it,maintaining their homogeneity in morphology and good stability in dispersion for the recovery and stripping processes.A pseudo-second model order is obtained for the extraction and stripping processes while the best results of stripping process are obtained at pH of 6.
