摘　　要：基于聚吡咯的光电性能和Zn_(3)In_(2)S_(6)的光催化活性,将聚吡咯与Zn_(3)In_(2)S_(6)相结合,以盐酸四环素为模板分子,将盐酸四环素的吸附-降解-光再生有效耦合,研究聚吡咯与Zn_(3)In_(2)S_(6)的配比、光照时间、淬灭剂等对盐酸四环素的吸附-降解-光再生过程的影响。结果表明,2%PPy/Zn_(3)In_(2)S_(6)对盐酸四环素的处理效果最好,吸附效率可达到76.63%,光照30 min,饱和吸附的2%PPy/Zn_(3)In_(2)S_(6)光再生效率可达到17.03%。Based on the photoelectric properties of polypyrrole and the photocatalytic activity of Zn_(3)In_(2)S_(6),polypyrrole and Zn_(3)In_(2)S_(6)were combined to effectively couple the adsorption-degradation-photoregeneration of tetracycline hydrochloride with it as template molecule.The effects of the ratio of polypyrrole to Zn_(3)In_(2)S_(6),illumination time and quencher on the adsorption-degradation-photoregeneration process of tetracycline hydrochloride were studied.The results showed that the treatment effect of 2% PPy/Zn_(3)In_(2)S_(6) tetracycline hydrochloride was the best, the adsorption efficiency could reach 76.63%,and the light regeneration efficiency of saturated adsorbed 2% PPy/Zn_(3)In_(2)S_(6)could reach 17.03% after 30 min of illumination.
