摘要
以氢氧化镁作为吸附剂处理含镍酸性废水的结果表明,该方法操作简便,镍去除率高,处理后废水中镍含量可以达到国家排放标准要求.氢氧化镁对Ni2+的饱和吸附量达1.2267g/g.氢氧化镁回收后,经轻烧处理变成氧化镁,仍可以处理含镍工业废水,且可多次使用.吸附等温线的测定和吸附产物的粉末X衍射分析结果表明,Mg(OH)2对Ni2+的吸附为典型的化学吸附.
The results of study on the use of Mg(OH)2 as a water treatment reagent to treat wastewater containing nickel ion indicated that Mg(OH)2 has an excellent performance to treat wastewater with Ni2+. The saturation adsorbing capability of Mg(OH) 2 is 1.267 g/g can be recycled by changing it into MgO at high temperature and used repeatedly to treat wastewater with Ni2+, the adsorption isotherm and XRD analysis of the adsorbed substance showed the adsorption of Ni2+ by Mg(OH)2 manifested the same chemical adsorption.
