摘要
以铝镁双金属离子低聚物为交联剂,制备了复合联膨润土,用于处理含重金属的有机废水.通过改变pH值、用量和处理时间等因素研究了镁铝交联膨润土对重金属及有机物质的吸附特性和处理效果.研究表明,膨润土用镁铝交联剂改性后吸附能力显著增强,对有机染料和重金属有较强的吸附性能,去除率均在96%以上.由于膨润土的储量大、价格低,是一类很有发展前景的优质廉价吸附剂.
Improve the bentonite with magnesium-aluminum low keggin-ion cross-linked agent to produce magnesium-aluminum cross-linked bentonite. Put it forward to deal with the wastewater containing heavy metals-ion and organism. We study the absorptive characteristics and the effection of the new product by changing certain factors, for example, the pH value,the time and so on. The tests show that the absorption ability is greatly improved,as far as the heavy metals-ion and organism doing is concerned. The anti-heavy metals ion and anti-organism dye rate could rise to 96%. Because of its big amount and low price,it will be considered as a kind of new absorbent under good development.
