摘要
研究了二氧化钛经马福炉烘烧固定化后作为催化剂,用紫外灯为光源,降解工业废水苯酚。实验得出:烘烧温度、二氧化钛掺杂物、降解液中添加物、粘合剂均对苯酚转化率有影响。结果表明:烘烧温度400℃,用淀粉作为粘合剂,降解液中加入双氧水,二氧化钛中掺入铁、镁、铜粉均对转化率有所提高。
This paper studies the photocatalysis degradation of phenol wastewater under UV ray with titanium dioxide, which has been burned and takes the shape of lump. The experimental results show that the parameters such as the burning temperature of TiO_2; material for adding to the solution; the glue of TiO_2 affect the conversion rate of phenol. It is clear from these results that the burn temperature of 400 ℃ and the addition of H_2O_2?CH_3COCH_3?Fe(NO)_3 to phenol solution can enhance catalytic activity.
