The effects of polyethylene oxide on species distribution and flocculating ability of polyaluminum chloride(聚氧化乙烯对聚合氯化铝形态分布及絮凝能力的影响)

本文研究了聚氧化乙烯(PEO)的引入对Al(III)的水解聚合过程、成品聚合氯化铝(PAC)中铝的形态分布及絮凝能力的影响。结果表明,PEO的引入使碱滴定过程中Al(III)的水解聚合过程提前,所制得的改性PAC抗酸性增加,含有更多的不能被Al-Ferron方法所解离-络合的形态,在室温下存放更为稳定。PEO的引入能明显提高PAC的絮凝能力,加快絮体沉降速度。两种引入方法中,先加入法的效果优于后加入法。...
