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 was shown that the reduction of Basic Green was enhanced by ultrasound. In all combined systems, the decolorization efficiency is more than 95%, but removal ratio of CODcr decreased with the increasing pH or initial dye concentration and increased with the increase of the amount of cast iron.
研究了pH值、铸铁用量和初始浓度对铸铁联合超声去除碱性绿去除率的影响。结果表明，超声可增强碱性绿的还原效果。在所有联合体系中，脱色效率均超过95%，但CODcr去除率随pH值或初始染料浓度的增加而降低，随铸铁用量的增加而升高。
