, 2000 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 ...

, 2017 通过对杭州西湖综合保护工程钱塘江引水范围内多个湖区水体和底泥中铝盐含量的调查分析,研究了工程絮凝剂余铝对西湖水体、底泥铝盐及沉水植物附着物的影响.结果表明：（1）引水工程输入的絮凝剂残余铝盐导致各湖区入水口水中铝离子含量普遍高于湖心,高出7.86%~288.55%不等,但底泥中Al_2O_3含量在整个湖区分布较为均匀;（2）约0.04~0.20 m/s流速下,沉水植物很容易成为残余铝盐絮凝物的附着受体;（3）秋、冬季水体中铝离子浓度较高,对西湖水生生物存在更大的生物潜在危害,有必要重视秋 ...
