摘要

  • 摘要: 采用溶胶凝胶法制备了氮掺杂二氧化钛光催化剂,用XRD、SEM、FTIR和粒度分析仪对催化剂进行了表征,并且在可见光作用下对曙红Y溶液进行了光催化降解实验。研究了催化剂的投加量、曙红Y的初始浓度、光照时间和pH对曙红Y溶液的光降解效果。结果表明,以可见光作光源,催化剂的投入量为0.4 g,曙红Y溶液的初始浓度为20 mg/L,光照时间为50 min,pH=4条件下,曙红Y溶液的降解率达98.87%。
    Abstract: Nitrogen-doped TiO2 were prepared by sol-gel method, and charactered by means of XRD, SEM, IR and particles size analysis. Photocatalytic degradation of wastewater from eosin solution was also studied by using nitrogen-doped TiO2 as catalyst and visible light as light source. The influences of the dosage of catalyst, concentration of eosin Y,photocatalytic reaction time and pH were investigated. The optimum conditions are found: the proper dosage of nitrogen-doped TiO2 catalyst is 0.4 g, concentration of eosin Y solution is 20 mg/L, the photocatalytic reaction time is 45 min,pH=4, decolorization rate of eosinY solution is 98.87 %.
