Preparation and characterization of La1_ xMn1_ yO3 piezocatalyst for removing waste drug pollutants in wastewater under the piezo-catalyst effect

Because of their non-biodegradability and harmful effects, the presence of many pharmaceutical components in an aquatic system degrades aquatic life. In this paper, the main aim is the synthesis and characterization of La1_ xMn1_yO3 nanostructures by applying the microwave irradiation method and its application as an efficient piezo catalyst to treat medical waste. Catalysts were characterized by a variety of techniques such as XRD, SEM, EDS, BET, and TEM. After that, the second part is the study of the piezoelectric performance evaluation of lanthanum manganite to degradation of the drugs waste such as Paracetamol (PCT) or acetaminophen, Tetracycline mono Hydrochloride (TCH), and Amoxicillin (AMX). Finally, the effect of various parameters such as catalyst dosage, initial concentration of drugs, pH, and ultrasonic power on degradation efficiency of Pharmaceutical waste was investigated. Prepared catalysts degrade up to 97%, 95%, and 90% of PCT, TCH, and AXM under ultrasonic vibration. Besides mechanism of degradation was conducted by the radical scavenger method.
