Polyvinyl alcohol matrix supported Europhobia antiquorum L activated carbon is analyzed for its applicability as an adsorbent for the removal of Methylene Blue dye from its aqueous solution. Effect of pH, initial dye concentration, dosage and temperature were studied. The PVA matrix supported AC adsorbs 91.67 mg/g of MB at 100 mg/L of initial dye concentration. It was analyzes with the help of pseudo first order, second order models. Collected data also analyzed with the help of Intra particle diffusion model to elucidate the mechanism. These kinetic parameters were compared for various dyes under different condition. Langmuir and Freundlich isotherm models were used to test the equilibrium data. The Langmuir monolayer adsorption capacity increases from 56.49 to 67.12 mg/g on increasing the room temperature from 30 to 50° C. The results this study proves that PVA supported EAC is a promising adsorbent for the remediation of textile effluent in a sustainable manner with a surface area of 739.5 m2/g.
