摘要/Abstract

摘要： 以钢渣为原料，通过共沉淀法制备Ca?Mg?Al?Fe层状双金属氢氧化物，对材料进行了表征，考察了其对甲基橙的吸附性能. 结果表明，所制材料结构规整、晶型良好，层状结构明显，对甲基橙的吸附符合Langmuir等温吸附模型，吸附过程符合拟二级动力学方程.

关键词: 钢渣, 层状双金属氢氧化物, 甲基橙, 吸附

Abstract: Ca?Mg?Al?Fe layered double hydroxides (LDHs) was synthesized via coprecipitation using steelmaking slag as raw material. The LDHs was characterized, and its absorption property to methyl orange was also studied. The results showed that the LDHs presented well-defined crystal structure and shape. The absorption process fitted Langmuir isotherm absorption model well, and the absorption kinetics followed a pseudo-second order kinetic model.

Key words: steelmaking slag, layered double hydroxides, methyl orange, adsorption
