摘　　要：研究了钢渣和改性粉煤灰对六价铬离子的去除效果。研究结果表明,钢渣对六价铬离子的去除效果不是很好。用氢氧化钙对粉煤灰进行高温活化后对六价铬有良好的去除效果。改性粉煤灰对六价铬的去除效果受粉煤灰的加入量、温度、振荡速度和废水初始pH值的影响。应考虑改性粉煤灰在工业上的推广应用。Modified fly ash and steel - slag were investigated to deal with wastewater contained with Cr^6＋ . The results show that the steel - slag has not very good effect on the removal of chromium. The fly ash which is modified with calcium hydroxide at high temperature has very good effect on the remove of Cr^6＋ .The removal effect of Cr^6＋ is affected by the addition amount of modified fly＇ash, temperature, shake speed and the initial pH value. It should be considered to dissemination and application of modified fly ash in industry.
