吸附材料处理重金属废水的研究

Research on Treatment of Heavy Metal Wastewater by Adsorbing Material

静态法研究了自制吸附材料对重金属离子的吸附性能,结果表明,吸附材料对铜离子和钴离子具有吸附能力。pH为6时,对钴离子吸附容量最佳,达0.267 mmol/g。使用硫酸溶液可实现重金属离子的解吸。通过反复吸附-解吸实验证明,自制吸附材料具有良好的重复使用性能。

The performance of adsorbing heavy metal ions by a kind of self-prepared adsorbing material was studied with a static method. The results of study have shown that this adsorbing material is capable of adsorbing copper ions and cobalt ions with the capacity of adsorbing cobalt ions being the best and that sulfuric acid solution can be used to desorb the heavy metal ions. The results of the experiment of repeated adsorption and desorption have shown that this self- prepared adsorbing material has good re -use performance.
