[ 1 ] - Preparation of ZnO nanocatalyst supported on todorokite and photocatalytic efficiency in the reduction of chromium (VI) pollutant from aqueous solution
In this research, a new effective photocatalyst was prepared by supporting ZnO on a Todorokite (TD). This catalyst was characterized by employing scanning electron microscopy (SEM-EDX) and X-Ray Diffraction (XRD) patterns. The optical properties of the samples were measured by diffuse reflectance spectroscopy (DRS). The purpose of using the ZnO/TD as a photocatalyst was to reduction Cr(VI), whi...
[ 2 ] - Optimization of Photocatalytic Reduction of Cr(VI) in Water with Nano ZnO/Todorokite as a Catalyst: Using Taguchi Experimental Design
In the present work, the solid-state dispersion method has been used to stabilize ZnOon Todorokite (TD). ZnO/TD catalysts have been characterized by SEM and XRD. Optimum process conditions were determined for the removal of Cr(VI) from water using the Taguchi fractional design method. Four controllable factors containing pH, photocatalyst amount, irradiation intensity, and <em...
[ 3 ] - Photocatalytic Degradation of Dye Pollutant in Synthetic Wastewater by Nano-Fe3O4 Based on Clinoptilolite Zeolite
Background & Aims of the Study: One of the most important environmental pollutants in the alcohol industry is sugar beet molasses. The wastewater of these industries causes the pollution of soil, surface water, and underground water. Iron oxide magnetic nanoparticles have attracted much consideration due to their unique properties, such as superparamagnetism, surface-to-volume ratio, greater su...
