Zeolites are the porous, negatively charged, and inorganic aluminosilicate adsorbent material. They possess large surface area and contain many ions exchange sites that make it very feasible for the removal of contaminates like metal or dye from industrial water using various techniques Among the various available techniques such as ion exchange, extraction, and reverse osmosis, adsorption is the most promising technique, as it is reliable, less destructive, and more economical. This paper reports the efficiency of catalysts, zeolite 4A, and amine-F-4A to remove methylene blue dye from aqueous solution. Zeolite 4A was amine functionalized using APTES. The synthesized material was characterized using FE-SEM, XRD, and FTIR. The motive was to increase the negatively charged species on the zeolite framework, to test whether the adsorption efficiency increased or not. Further it was tested for its efficiency to remove colored pollutants from synthetic wastewater. The motive of the study was to compare the adsorption efficiency of raw zeolite and modified zeolite. The results favored the usage of raw zeolite alone without any chemical treatment to remove the colored pollutant. Raw zeolite alone can be a self-sufficient material in removing methylene blue dye from wastewater.
