文摘

•: ZnO degrades ethyl paraben faster than P25 TiO₂ under solar radiation.
•: Paraben and ZnO concentration, reaction time, humic acid in water affect kinetics.
•: Hydroxylated and dealkylated by-products are formed early during the reaction.
•: By-products are more stable but less estrogenic than ethyl paraben.
•: Dissolved zinc concentration in the liquid phase is minimal (<12 mg/L).
