摘要: Abstract In this study, the removal of six commonly detected pharmaceuticals and personal care products (PPCPs), including carbamazepine (CBZ), ibuprofen (IBU), sulfadiazine (DIA), sulfamethoxazole (SMX), sulfamethazone (SMZ) triclosan (TRI), were conducted with E. crassipe Pistia stratiotes at high (10 mg/L) low (0.8 mg/L) initial concentrations. After 13 d incubation, P. can stimulate selected PPCPs in both concentration sets, but efficacy was much lower set due to toxic effect aquatic plants. Slight photodegradation observed control set, while synergistic effects biodegradation, plant uptake adsorption (for TRI) presence crassipe. The be categorized into four groups according their characteristics microcosm systems: (1) moderately photodegradable compounds: DIA, SMZ SMX, (2) highly biodegradable compound: IBU, (3) adsorptive TRI, (4) recalcitrant CBZ. pseudo-first order kinetics model fits PPCP degradation data well rate constants half-lives calculated as 0.036–0.585 1/d 1–19 d, respectively. showed higher ability than for most statistically significant difference constants. With adequate allocation biomass, rational residence time efficiency wetlands receiving PPCP-containing effluents could expected.
