碳纳米管对水中硫化物吸附性能的研究

Study on the Adsorption Properties of Sulfide from Water by CNTs

本文采用碳纳米管对水中的硫化物进行吸附研究,考察了吸附时间、pH值、CNTs的使用量、硫化物的浓度等对吸附效果的影响。通过吸附等温线实验和吸附动力学实验,探讨了碳纳米管对水中硫化物的吸附规律,吸附数值遵循Langmuir吸附等温式,吸附过程符合Bangham吸附速率方程。并对碳纳米管的再生进行了研究,为处理含硫化物废水提供了新的途径。

adsorption adsorption discussed. The effects of adsorption time, pH, the amount of CNTs, the concentration of Sulfide on the of Sulfide were kinetics experi The adsorption investigated. By conducting sulfide adsorption isotherms experiment and ment, the adsorption properties of Sulfide from Water by CNTs were of sulfur by CNTs met the Langmuir isotherm equation and Bangham equation.And the regeneration of carbon nanotubes was studied in this article in order to provide a new way to deal with sulfide-containing wastewater.
