摘　　要：四环素类抗生素因其良好的药用价值被广泛用于畜牧和医疗等行业。大量的四环素类抗生素随着排泄物流入生态环境,造成生态系统失衡,并对人类健康构成巨大威胁。因此,实现四环素的有效降解具有重要意义。光催化技术以成本低和无二次污染等优势成为降解四环素抗生素最具潜力的技术之一。根据四环素类抗生素的基本结构和毒性的研究情况,对窄带隙半导体光催化剂用于四环素类污染物的研究及性能提升进行学术分析归纳,根据科学研究的趋势提出未来研究方向。Tetracycline antibiotics are widely used in animal husbandry and medical industry,because of their good medicinal value.A large number of tetracycline antibiotics are introduced into the ecology with the logistics,which leads to the imbalance of the ecosystem,and poses a great threat to human health.Therefore,it is of great signifi cance to realize the eff ective degradation of tetracycline.Photocatalytic technology has become one of the most potential technologies for degradation of tetracycline antibiotics because of its low cost and no secondary pollution.This paper studies the basic structure and the toxicity of tetracycline antibiotics,conducts academic analysis and induction on the research and performance improvement of applying narrow band gap semiconductor photocatalyst to tetracycline pollutants,and puts forward the research prospect according to the trend of scientifi c research.
