Enhanced dye removal using polymeric nanocomposite through incorporation of Ag doped ZnO nanoparticles: Synthesis and characterization.

A facile method was approached to synthesize a new series of highly porous polyethylene glycol (PEG) and Ag-ZnO (AZO) grafted polyaniline (PANI) nanocomposites (PAPE/AZO) for investigation of the adsorption behavior of brilliant green dye (BG). The compositions of Ag (1, 3 and 5%) in AZO were varied to assess the influence of bimetallic oxide incorporation. The nanocomposites were characterized by FTIR, XRD, SEM and TEM analyses.

Polymeric nanocomposites for the removal of Acid red 52 dye from aqueous solutions: Synthesis, characterization, kinetic and isotherm studies.

Polymeric nanocomposites polyaniline-polyvinylpyrrolidone (PAPV) and polyaniline-polyvinylpyrrolidone-neodymium/zinc oxide (PAPV-NZO) were synthesized for the effective dye removal through adsorption process. Neodymium doped zinc oxide (NZO) with various proportions of neodymium were prepared by chemical co-precipitation method and incorporated into the copolymer matrix via oxidative polymerization technique. NZO nanoparticles were characterized by X-ray diffraction (XRD) and the morphological features, and functional group linkages of the PAPV-NZO were confirmed by scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR) analyses.
