改性粉煤灰处理工业废水中镉离子

Research on Disposing Heavy Metal Ions Such as Cd^(2+) in Waste Water with Modified Fly Ash

本实验以粉煤灰为主要原料,经水浸、酸浸、碱浸后,掺入少量的改性剂,煅烧,老化,晶化,活化后制备成新型的吸附材料,用其处理模拟工业废水中的某些重金属离子,如镉。因此,此课题的研究有着重要的经济价值和社会价值。

A new adsorption matter was prepared via immersing fly ash in turn in water, acid and alkaline,and mixing modifier agent and then burning, ageing, crystallizing and activating. The material was used for treating some heavy metal ions such as cadminm in industrial waste water. Therefore,the subject has very important economic value and social value.
