Enhanced photocatalytic degradation of 2,4-dichlorophenoxyacetic acid from freshwater and industrial wastewater using TiO₂-CuO-clay soil nanocomposites.

ABSTRACT: 2,4-Dichlorophenoxyacetic acid (2,4-D) is a synthetic herbicide used to control weeds and enhance agricultural productivity. However, it is toxic and carcinogenic, posing significant risks to environmental pollution and human health. This study investigates the effectiveness of TiO2-CuO-clay soil nanocomposites in the photocatalytic degradation of pesticides from Ziway Lake and industrial wastewater. The two sets of composites were synthesized with different concentrations of TiO2-CuO-clay soil: the first with a ratio of 2:3:7 (TiO2, CuO and clay soil), and the second with a ratio of 4:3:5 (TiO2, CuO and clay soil). The mixture was treated with microwave digestion at 150 °C for 10 min, followed by filtration and calcination at 720 °C for 6 h in a muffle furnace. The morphology and the part
