modifiedOrangepeeh Hg2+ adsorption
为了了解改性橙皮对废水中Hg2＋的吸附作用,通过静态吸附实验,考察了离子初始浓度、吸附时间等因素对Hg2＋吸附的影响。试验结果表明,化学改性的橙皮对废水中的Hg2＋有一定的吸附能力。在温度50℃,初始浓度为10μg.L-1、搅拌30 min、投加量为20 mg/L的条件下,Hg2＋的去除率可达到96.66%。

Adsorption of Hg2＋ by modified Orange peel was studied. The effects of initial Hg2＋ concentration, contact time and so on adsorption were investigated. The results indicated that modified Orange peel had good adsorption to Hg2＋. In condition of 50℃, the initial concentration of 10μg.L-1, contact time was 30 min, 20 mg/L modified Orange peel, the adsorption rate of Hg^2＋ could be up to 96.66 %.
