چکیده مقاله:

Removing toxic organic matter is one of the important tasks in wastewater treatment. Recently, heterogeneous catalysts are used to activate peroxymonosulfate and hydrogen peroxide in advanced oxidation processes (AOP’s) based on sulfate radicals and hydroxyl radicals to remove these substances. In this research, lanthanum perovskite catalysts with some transition metals were prepared by citric acid sol-gel method and their performance in advanced oxidation process of medicinal pollutant ciprofloxacin was investigated using two oxidants, peroxymonosulfate and hydrogen peroxide. It was found that the prepared catalysts had better degradation performance in the presence of promonosulfate. According to the results, the prepared LaCoO۳ perovskite catalyst removes up to (۷۱%) of the peroxymonosulfate oxidant and up to (۳۹%) of the medicinal pollutant with the hydrogen peroxide oxidant.
