摘要
粉煤灰是一种可再资源化的工业固体废弃物,在建材、化工、农业和环保等领域都有广泛的用途。本文介绍了当前粉煤灰及其改性产品在处理含铬水溶液中的应用现状,讨论了温度、pH值、接触时间、铬离子浓度和粉煤灰用量对粉煤灰吸附性能的影响,介绍了粉煤灰对Cr(Ⅵ)和Cr(Ⅲ)的去除机理。
Fly ash is a kind of reusable industrial solid waste,which has been widely used in the areas of building materials,chemical engineering,agriculture and environmental protection.This paper introduces the current application status of fly ash and its modification production in chromium containing aqueous solution treatment,discusses the effects of temperature,contacting time,pH value,chromium density and dosage of fly ash on its absorption performance,and summarizes the removal mechanism of Cr（Ⅵ） and Cr（Ⅲ） by fly ash as well.
