超声增强对碱性品绿染料的降解

Ultrasound for increased degradation of the Basic Green

研究了溶液的pH、铸铁用量及初始浓度对碱性品绿在超声和铸铁联合作用下的降解情况。结果表明,超声的作用有助于提高染料的降解率。在联合作用的下,脱色率都在95%以上,但CODcr的除去率随溶液pH和溶液浓度的增加而减少,随铸铁用量的增加而增加。

The effect of pH, amount of cast iron and initial concentration on the removal ratio of Basic Green by cast iron combined with ultrasound was investigated. It has been shown that reduction of Basic Green can be enhanced by ultrasound. In all combined systems, decolorization efficiency is more than 95%, while the removal ratio of CODcr decreases with the increasing pH or initial dye concentration and increases with the increase of the amount of cast iron.
