负载TiO_2杏仁壳活性炭对亚甲基蓝的光解研究

Photolysis of Methylene Blue by the Almond Shell Activated Carbon Carried TiO_2

研究了负载TiO2杏仁壳活性炭对亚甲基蓝的光解催化效果。结果表明,在室温下、pH值5.0亚甲基蓝初始浓度10.0 mg/L 50.0 mL溶液,加入负载TiO2杏仁壳活性炭100.0 g/L和30%H2O220.0 mL/L,用24 W紫外灯光照射60 min,亚甲基蓝降解率96.75%。对于光解亚甲基蓝负载TiO2杏仁壳活性炭具有与商业纳米TiO2P25近似效果。

The almond shell activated carbon loaded TiO2 was used for photolysis of methylene blue. Experimental results showed that under the optimum conditions of the initial methylene blue concentration of 10.0 mg/L, pH 5.0, 30% H2O2 20. 0 mL/L, the dosage of almond shell activated carbon loaded TiO2 100.0 g/L and the UV light irradiation 60 min, the photolysis ratio reached 96.75%. The studied activated carbon possessed nearly the same properties of the commercial TiO2P25.
