| 摘 要： | 运用化学沉淀-原位复合法制得氢氧化镁/活性炭复合材料(Mg(OH)2/AC),对其比表面积和XRD谱进行了表征,考察了该复合材料对普拉红B的脱色性能.结果表明,在293～313 K下,Langmuir模型和Freundlich模型都能很好地描述Mg(OH)2/AC对普拉红B的等温吸附过程,而Langmuir模型更为合适...

| Abstract: | Magnesium hydroxide/activated carbon composite was prepared by chemical precipitation & compounding in situ. The surface area and poresize distribution of the composite were characterized. The removal of weak acid red B by the composite was investigated. Be superior to Freundlich model, Langmuir model fit to the adsorption of the dye at 293~313 K. Orthogonal experiments showed that the initial concentration of solution was the most important factor. The optimum adsorption effect was achieved under the following conditions: adsorption of solution with initial concentration of 250 mg/L at 313 K for 90 min by 0.1 g Mg(OH) 2/AC. |
