Synthesis of cobalt oxide catalyst for PMS activation on organic dye removal

This study was conducted to evaluate the catalyst efficiency to activate peroxymonosulfate for the removal of dyes, mainly Methyl Violet, Toluidine Blue O, and Acid Orange 7. Dyes, particularly those used in the textile industry, are considered organic pollutants. The discharge of wastewater from...
