摘要：

用聚二甲基二烯丙基氯化铵(PDMDAAC)改性高炉渣，研究了PDMDAAC改性高炉渣去除模拟印染废水中分散染料和活性染料的性能。结果表明，PDMDAAC改性高炉渣去除分散和活性染料的能力远大于原渣；研究了振荡时间、温度和pH对改性高炉渣处理效果的影响，结果表明，温度对去除效果影响很小，而振荡时间和pH的影响比较大。

Abstract:

PDMDAAC is used to modify blast furnace(BF) slag. The adsorption behaviors of PDMDAAC-BF slag on dispersive dyes and activated dyes are investigated. The experimental results show that the removal rates of both kinds of dye by using PDMDAAC-BF slag are much better than that of BF slag without being modified. It is indicated that temperature has only little impact on the removal rates of both kinds of dye while the reaction time and pH have much more impact.

Key words: polydimethyldiallylammoniumchloride, modification, blast furnace slag, dispersingdye, activated dye
