| 520 | _aThe applicability of green synthesized copper and silver nanoparticles incorporated in natural clinoptilolite-mordenite zeolite and montmorillonite bentonite using pineapple juice extract as an environmentally and economically friendly adsorbent for the removal of hazardous methylene blue dye from wastewater was evaluated. Catalytic experiments showed efficiency of the catalysts in the process of complete oxidation and reduction, the approach of adsorption coupled with catalytic degradation was applied for the highly efficient removal of methylene blue by using natural aluminosilicate nanocomposites. H2O2 was added to initiate the catalytic oxidation process and NaBH4 for the reduction process. Degradation process in the presence of H2O2, finally leading to the complete removal of pollutants without the requirement of more adsorbents. Pseudo-second-order equation fitted the experimental data well for pure zeolite and copper zeolite nanocomposite and the adsorption of silver zeolite, pure bentonite, copper bentonite and silver bentonite nanocomposites follows the pseudo first-order kinetics. Based on the SEM results the value of the adsorption capacity reveals that the natural aluminosilicate nanocomposites are efficient. The results have proven that the adsorbent nanocomposites materials can be effectively employed for the removal of the dye methylene blue from the waste waters and these materials are abundantly available. | ||
