Removal of Methylene Blue Dye from Aqueous Solution using PDADMAC Modified ZSM-5 Zeolite as a Novel Adsorbent

In the present work, we modified ZSM-5 zeolite using a bio polymer poly (diallyl dimethyl ammonium chloride) and employed it for removal of cationic dye, methylene blue from aqueous solution. The chemical physical properties were investigated XRD, FTIR, SEM, TEM, nitrogen adsorption, TGA 27Al NMR. Modified possesses high surface area pore diameter which was confirmed TEM adsorption analysis. Adsorption on by batch technique. effect different parameters such as dosage, initial concentration, temperature, pH contact time process discussed. Maximum capacity (4.31 mg/g) achieved 0.1 g at optimum conditions (initial dye concentration: 10 mg/L, 10, temperature: 30 °C time: 300 min). experimental data fitted into Langmuir Freundlich models results indicate that followed isotherm. Kinetic pseudo-first-order pseudo-second-order models. analysis indicates model is more suitable to describe MB zeolite. reusability test suggests adsorbent could be reused least six times without significant loss in efficiency.
