凹凸棒土对废水中Pb(Ⅱ)吸附的初步研究OA北大核心CSTPCD
Primary study on absorption behavior of Pb(Ⅱ) on attapulgite clay
研究了凹凸棒土对重金属离子Pb(Ⅱ)的吸附性能.考察了平衡时间、凹凸棒土用量、pH等对Pb(Ⅱ)在凹凸棒土上吸附性能的影响.结果表明,凹凸棒土对Pb(Ⅱ)具有较强的吸附性能,在Pb(Ⅱ)质量浓度为9.375×10-3g/L,6h时达到吸附平衡；凹凸棒土质量浓度在005 g/L时,吸附效果较好；Pb(Ⅱ)在凹凸棒土上的吸附受pH影响较大,在pH为6.5～9.5时吸附率达到最大.
The absorption behavior of Pb(Ⅱ) on attapulgite clay was studied.The effects of equilibrium time,attapulgite clay dosage,pH on the absorption behavior of Pb(Ⅱ) on attapulgite clay were investigated.The results showed that attapulgite clay had high absorption ability,and the absorption equilibrium could be attained at 6 h when Pb(Ⅱ) concentration was 9.375×10-3 g/L.The optimal adsorption effect could be obtained when the mass content of attapulgite clay was 0…查看全部>>
