The structural, morphological, and surface characteristics of the nanocomposite were investigated using X\u2010ray diffraction, Williamson\u2013Hall analysis, Fourier transform infrared spectroscopy (FTIR), field\u2010emission scanning electron microscopy, energy\u2010dispersive X\u2010ray spectroscopy, zeta potential measurements, and Brunauer\u2014Emmett\u2013Teller and Barrett\u2014Joyner\u2013Halenda (BET\u2013BJH) surface area analysis. The incorporation of PVPP resulted in enhanced surface properties, increased negative surface charge, and modified morphology. The synthesized nanocomposite exhibited a crystallite size of 15.3\u00a0nm, a lattice strain of 0.43%, and a zeta potential of \u221230\u00a0mV, favoring the adsorption of cationic dye molecules through electrostatic attraction. BET\u2013BJH analysis revealed a mesoporous structure with a Type IV adsorption isotherm, a surface area of 25\u00a0m\n                    <jats:sup>2<\/jats:sup>\n                    \/g, and an average pore diameter of 6.05\u00a0nm, providing numerous active adsorption sites. Adsorption studies demonstrated rapid removal of methylene blue, with the characteristic absorption peak at 664\u00a0nm disappearing completely within 5 min, corresponding to 99% removal efficiency. Industrial wastewater samples also showed complete elimination of dye\u2010related absorption peaks after treatment. FTIR analysis of the dye\u2010loaded adsorbent indicated the involvement of electrostatic interactions, hydrogen bonding, and\n                    <jats:italic>n<\/jats:italic>\n                    \u2013\n                    <jats:italic>\u03c0<\/jats:italic>\n                    interactions.
