Abstract
Using glass,aluminum and nickel mesh as the carrier,which were common industrial materials,and aniline as nitrogen source,different materials loaded nitrogen-doped titanium dioxide were prepared by solgel method.The photocatalytic degradation capacity of acid fuchsin which representing dyeing wastewater was investigated.The results showed that the best N/Ti ratio of glass,aluminum and nickel mesh loaded Ani/TiO2 were 0.250,0.040 and 0.040,respectively.Nitrogen doping could improve the photocatalytic activity of titanium dioxide in the sunlight.The best pH of their photocatalytic degradation capacity were all 6 to 8,their best initial concentrations were 10 mg/L,12 mg/L and 12 mg/L,respectively,and their photocatalytic activity would all decrease with the increase of the solution depth.All of the best concentrations of ferric nitrate were 0.5 × 10-5 to 1.0 × 10-5 mol/L.Overall,the photocatalytic activity of glass loaded Ani/TiO2 was the highest,while nickel mesh loaded Ani/TiO2' s was the lowest.关键词
