摘　　要：以壳聚糖作为催化剂载体,采用浸渍法和混合法制备出壳聚糖负载型光催化剂,并进行了扫描电镜和红外光谱表征。以自然光为光源、四环素为底物,探究了壳聚糖负载型光催化剂的光催化降解性能。研究结果表明:当浸渍时间为2 h,浸渍比为1∶1,浸渍温度为常温,所制备的壳聚糖负载酞菁钴的光催化效果最好且易回收分离,即光照60 min,对四环素的光催化降解率达70%。Chitosan supported photocatalyst was prepared by impregnation and mixing method,and the photocatalysts were characterized by SEM and IR.Using natural light source and tetracycline as substrate,the photocatalytic degradation performance of chitosan supported photocatalyst was investigated.The results showed that when the impregnation time was 2 h,the impregnation ratio was 1∶1,and the impregnation temperature was normal,the prepared chitosan supported cobalt phthalocyanine had the best photocatalytic effect and was easy to recover and separate.The photocatalytic degradation rate of tetracycline was up to 70% under 60 min illumination.
