Advanced oxidation processes (AOP), based on the formation of highly reactive radicals, are able to degrade many emerging organic environmental contaminants such as tetracycline (TC) in wastewater. In peroxymonosulfate(PMS)-advanced oxidation process(AOP), the presence of a Heterogeneous catalyst is required. Among of them, perovskite( as an advanced material) is promising due to its tunable composition in cationic positions and structural stability. In this research, LaMnO3 perovskite nanocatalyst was synthesized by sol-gel method via complex agents. the LaMnO3 nanoparticles were successfully prepared, as proven using different spectroscopic techniques including XRD, FESEM, EDS, BET, XPS and TG/DTG. Finally, the performance of LaMnO3 nanoparticles in degrading tetracycline in water during advanced oxidation process for PMS activation was investigated. The results shows that this method is very good for treatment of wastewater containing this dangerous pollutant. It is shown the tetracycline pollutant in the wastewater can be reduced from 25 and 50 ppm by 62.7% and 70.2%.
