Valorization of Lignocellulosic Wastes Material for Efficient Adsorption of a Cationic Azo Dye and Sludge Recycling as a Reinforcement of Thermoplastic Composite

This work explored the adsorption of Malachite Green (MG) dye by Acorn Pericarp (AP) in context biomass valorization. The was analyzed Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction. capacity under optimal experimental conditions studied at different adsorbent doses, initial concentration times pH. results presented this on kinetics MG showed that pseudo-first-order model (R2 = 0.9971) better described 10−5 M. isotherms followed Langmuir isotherm 0.9889). thermodynamic study is endothermic (ΔH° > 0) spontaneous (ΔG° < 0). For a sustainable industry, sludge converted into reinforcement polystyrene using in-situ polymerization with 10% weight filler. A morphological structural analysis performed SEM FTIR, characterization AP incorporated well PS matrix.
