Abstract

Background/Objectives: The current study is focused on the synthesis of spinel catalyst (Co, Ni)₃O₄. This catalyst was used in removal of two textile dyes from wastewater that are charged from local textile factory. Methods/Statistical Analysis: This catalyst was synthesized using co-precipitation method. The obtained materials was calcinated in a furnace oven at temperature of 600⁰C for four hours. Then produced catalysts were investigated using different techniques such as Powder X-Rays Diffraction (PXRD), Atomic Force Microscopic (AFM). The treated industrial wastewaters that were used in this study were collected from the local textile factory in Hilla city (Iraq). Findings: The photocatalytic activity of the synthesized catalysts was investigated by following the photo catalytic removal of both Bismarck Brown G, (BBG) dye and Reactive Yellow145 dye (RY145) from the industrial wastewaters at normal atmospheric conditions. After one hour of reaction, the efficiency of dye removal was 94.60% and 31.11% for Bismarck Brown G and Reactive Yellow 145 dye respectively. Applications/Improvements: This study gives promising results in concern with treatment of industrial wastewaters before they are charged into the nearest water streams or in some cases they can be recycled to be used for industrial purposes at the same factory or at any other industrial unit.
