Abstract ZnIn₂S₄/g-C₃N₄ composite catalyst prepared by hydrothermal method was applied to catalyze trace carbamazepine (CBZ) in river water under solar irradiation. The effect of suspended solid (SS), inorganic salt (IS), and dissolved organic matter (DOM) in real river water on the catalytic activity of ZnIn₂S₄/g-C₃N₄ composite catalyst and the experimental effect in dynamic tests of ZnIn₂S₄/g-C₃N₄/pumice loaded catalyst to CBZ were both analyzed. It indicated that the catalytic activity of ZnIn₂S₄/g-C₃N₄ with mass ratio of 20:1 was higher than that of pure ZnIn₂S₄ in CBZ photocatalytic degradation. The heterogeneous structure of ZnIn₂S₄/g-C₃N₄ accelerated the separation of electron-hole pairs and simultaneously prohibited their recombination. An increase in the amount of mesopore and an increase in specific surface area of ZnIn₂S₄/g-C₃N₄ both could improve the catalytic activity of the catalyst effectively. The influence of water quality parameters on the catalyst activity in an increasing sequence was DOM>IS>SS, and the constant of photocatalytic rate of CBZ in filtered river water increased 13times than that in raw river water. CBZ of an initial concentration of 100μg/L was completely degraded with a dosage of 125mg/L catalyst and under 240min solar irradiation. In dynamic tests, the photocatalytic efficiency of CBZ decreased gradually with an increase in the flow rate of water. Under 4cycles with a flow rate of 5mL/min, the rate of removal and the rate of mineralization of CBZ by ZnIn₂S₄/g-C₃N₄/pumice catalyst were 86.4% and 43.9%, respectively.

Key words： carbamazepine ZnIn₂S₄/g-C₃N₄ photocatalysis kinetics dynamic test
