| Abstract | ||
| Pollutant removal is critical, as evidenced by the need for clean water, the rise in industrial effluent, and environmental pollution. One very efficient way to get rid of impurities from water and industrial effluent is to use zeolite removal. TiO2 is one of the special photophysical characteristics of zeolite, which is distinguished by its numerous microscopic pores, high absorption capacity, and thermochemical stability. Sol-gel was used to synthesise zeolite and TiO2 quantum dots (TQD) with diameters ranging from 307 to 48 nanometers. In this work, zeolite microparticles were treated with TiO2 nanoparticles. The zeolite/TiO2 composites were assessed using SEM, diffuse reflectance spectroscopy, Brunauer-Emmett-Teller, and X-ray diffractometer investigations. The results showed that the presence of TiO2 nanoparticles reduces the specific surface area. However, it results in the ability to absorb ultraviolet rays. Increasing the amount of TiO2 will cause the absorption edge to move. The photocatalytic properties of the compounds were evaluated using Blue Dianix dye removal analysis. Zeolite-TQD, with a specific surface area of 292.39 m2/g and a band gap energy of 3.57 eV, is the most effective material. Evidence of enhanced photocatalytic performance was obtained through analysis of spent chemical oxygen. We also confirmed the photodegradation rate of real industrial effluents using COD limitations specified in the Egyptian Environmental Law. Nine recycled zeolite-TQD samples were examined using COD measurements. | ||
