Synergistic sonocatalytic degradation of carbamazepine and 17α-ethinylestradiol in the presence of carbon nanotube yarn.

ABSTRACT: Pharmaceuticals such as carbamazepine and endocrine disruptors such as 17α-ethinylestradiol are persistently present in aquatic environments and pose serious ecological and human health concerns due to their chemical stability and limited removal efficiency by conventional wastewater treatment methods. In this study, a carbon nanotube yarn catalyzed high-frequency ultrasonic system was developed to synergistically enhance the degradation of carbamazepine and 17α-ethinylestradiol. carbon nanotube yarn, which is well known for its high surface area, chemical stability, and good electrical conductivity, was applied to a 970 kHz ultrasonic reactor to amplify acoustic cavitation and promote ^•OH generation. Kinetic analysis confirmed that the combined ultrasonic US-assisted catalytic
