通过Ti(OC4H9)4水解sol-gel法和煅烧技术,在不同的BW11投加量下制备BW11/TiO2复合型材料,通过在125W高压汞灯照射下,研究BW11/TiO2复合光催化剂对水中难降解重金属Cr6+的光催化降解效果.
实验结果表明：在投加10mL0.05molBW11时制备的BW11/TiO2复合光催化剂具有最好的光降解效果；随着催化剂初始浓度的增加降解率增加,当初始浓度达到10g/L时,继续增加初始浓度对最终降解效果影响不大；当水中存在亚甲基蓝时,会降低铬的降解率,随着亚甲基蓝浓度的增大,降解率变化不大；不同浓度甲基橙对铬的降解影响不同,先随着甲基橙浓度的增大降解率降低,当浓度达到40mg/L后降解率随着浓度的增大而增加,当甲基橙浓度达到50mg/L后铬的降解率基本不变.

Answer 1

Through the Ti ( OC4H9 ) sol-gel 4 hydrolysis method and calcining technology,in different dosage of BW11 to prepare BW11/TiO2 composite material,through the 125W high pressure mercury lamp irradiation,BW11/TiO2 composite photocatalyst for water difficult to degrade heavy metals Cr6+ photocatalytic degradation effect.The experimental results show that:after adding 10mL0.05molBW11 prepared BW11/TiO2 composite photocatalyst has the best photocatalytic degradation effect; with the increase of initial concentration of catalyst degradation rate increased,when the initial concentration reaches 10g/L,continue to increase the initial concentration of the final degradation effect is small; when the water in the presence of methylene blue,will reduce the degradation rate of chromium methylene blue,with the concentration increased,the degradation rate of change is not big; different concentration Methyl Orange Degradation Effect of chromium in different,first with the increasing concentration of methyl orange degradation rate decreased,when the concentration reaches 40mg/L degradation rate increased as the concentration increases,when the concentration of methyl orange reached 50mg/L CR degradation rate unchanged.Key words:composite photocatalyst; BW11/TiO2; Cr6+; photocatalytic degradation
