摘　　要：文章利用乙二胺四乙酸镁-铝插层水滑石(LDHs),制备可吸附重金属离子的透水混凝土,研究吸附材料、重金属离子种类和浓度对吸附性能的影响。采用微观测试手段,揭示了吸附重金属离子的微观机理。试验结果表明:可吸附重金属离子的透水混凝土的吸附性能优于普通透水混凝土,且对重金属离子的吸附具有选择性。Magnesium ethylenediaminetetraacetate-aluminum intercalated Layered Double Hydroxide(LDHs)was used to prepare pervious concrete that can adsorb heavy metal ions.The influence of adsorption materials,types and concentrations of heavy metal ions on adsorption properties were studied.The microscopic mechanism of adsorption of heavy metal ions was revealed by means of microscopic testing method.The test results show that the adsorption performance of pervious concrete that can adsorb heavy metal ions is better than that of ordinary pervious concrete,and the adsorption of heavy metal ions is selective.
