中文摘要:
      将Al-TiO2光催化剂负载于金属钛板表面,以苯酚为目标污染物,考察负载后光催化剂的活性及持久耐用性. 采用与Fenton技术联用补偿光催化剂负载后活性的降低,探讨负载的Al-TiO22与Fenton联用的效果及影响因素. 结果表明: 负载于金属钛板的Al-TiO2活性有所降低,但持久耐用;Al-TiO2与Fenton联用,在1h内苯酚和COD的去除效率分别从29.88%和23.65%提高至95.86%和93.89%,分别提高了65.98%和70.24%;协同体系中H2O2投加量0.2mL·L-1,Fe2+浓度0.6mmol·L-1,改性纳米TiO2光催化剂固定量0.36g,反应初始pH为4,同时光源达300W时苯酚1h内能完全降解.
英文摘要:
      Al-TiO2 photocatalyst were supported on the titanium plate surfaces,and then the photocatalyst’s activity and persistent durability were studied with phenol as the target pollutants. Effect and influence factors were investigated between the supported Al-TiO2 and combined Fenton,by using techniques associated with Fenton to compensate the activity reduction of photocatalytic after being supported. The results showed that the Al-TiO2 activity was decreased a little by being supported on the titanium plate surfaces,but it appeared more durable. The removal efficiency of phenol and COD were increased to 95.86% and 93.89% by Al-TiO2 supported and Fenton supported within 1h from 29.88% and 23.65%,respectively,with the increasing ratio of 65.98% and 70.24%. Phenol was completely degraded within 1h with the condition of collaborative system H2O2 dosage of 0.2mL·L-1,Fe2+ concentration of 0.6mmol·L-1,fixed amount of modified nano-TiO2 photocatalyst of 0.36g,the initial pH of 4,and the light power up to 300W.
