| 摘 要： | 利用沸石吸附法去除重金属废水中以络离子形态存在的铜。实验考察了沸石用量、振荡时间、p H和温度对吸附效果的影响 ,探讨了吸附作用机理。结果表明 ,沸石对 Cu( HN3 ) 2 + 4 有良好的吸附性能 ,废水 p H、温度和吸附时间是影响吸附效果的主要因素。在 Cu( HN3 ) 2 + 4 浓度低于 5 0 mg/L时 ,吸附规律基本符合 Freundlich模式 ,高于 5 0 mg/L时 ,不能满足常规吸附规律

| Abstract: | The adsorption of permutite was used to remove Cu(HN 3) 2+ 4 in the heavy metals wastewater. The effect of shaking time, temperature and pH value on the adsorption Cu(HN 3) 2+ 4 onto permutite was investigated. The mechanism for the adsorption was studied. The results indicate that shaking time, temperature and pH value are the main factors to affect adsorption of Cu(HN 3) 2+ 4. The adsorption of Cu(HN 3) 2+ 4 on to permutite can be described by Freundlich models when the concentration of Cu(HN 3) 2+ 4 under 50mg/L -1 . |
