Chloroacetanilide herbicides are widely used in the agricultural sector throughout world. Because of their poor biodegradability, high water solubility, and long persistence, chloroacetanilide have a potential to contaminate water, conventional treatment processes do not ensure sufficient removal. Therefore, heterogeneous photocatalysis using TiO2/UV-A was investigated for degradation alachlor,...
