“…Among various AOPs, TiO 2 heterogeneous photocatalysis has been proved to be a promising destructive technology to decontaminate water-soluble refractory pharmaceuticals efficiently and cost-effectively [13,14], due to the process can be carried out under mild condition [15]. The possibilities as well as the mechanisms of the photocatalytic degradation of some pharmaceuticals have been reported [16,17]. However, most studies were mainly focused on the elimination of parental compounds [17][18][19], although some degradation products were identified to be more toxicity to the aquatic ecosystems and the public health [20].…”
