纳米ZnFe_2O_4光催化降解活性艳红X-3B的研究

Photocatalytic degradation Reactive Brilliant Red X-3B by using nano-ZnFe_2O_4

采用水热共沉淀法制备了纳米铁酸锌催化剂,考察了反应时间、催化剂用量、初始浓度、起始pH及酸根阴离子种类和温度等对光催化降解活性艳红X-3B的影响。结果表明,在高压汞灯照射下,45℃,光催化剂纳米ZnFe_2O_4用量6 g/L,pH=2,降解100 m L浓度30 mg/L活性艳红X-3B溶液60 min,其降解率可以达到80.11%。

Nano-Zinc ferrite were prepared by hydrothermal coprecipitation method. Zinc ferrite as catalyst to photocatalytic degrades Reactive Brilliant Red X-3B. The effection of reaction time,amount of catalysts,initial concentration,initial pH and different anions,different temperatures were studied. The results showed that under the high pressure mercury light,45° C,concentration of catalyst is 6 g/L,using nitric acid to regulate initial pH = 2,degrade 100 mL 30 mg/L Reactive Brilliant Red X-3 B,the degradation rate can be reached 80. 11% in 60 min.
