Adsorption of Rhodamine B on Corn Cob-based Porous Carbon

以玉米芯基多孔炭为吸附剂,研究玉米芯基多孔炭对废水中罗丹明B染料的吸附。探讨了玉米芯基多孔炭的质量、吸附时间、罗丹明B染料初始质量浓度、温度和pH值对多孔炭吸附效能的影响。本实验研究了玉米芯基多孔炭对染料罗丹明B的最佳吸附条件,并对吸附热力学机理及动力学机理进行了研讨,为废水中罗丹明B的去除提供相应的理论基础。

The adsorption of Rhodamine B dye in waste water by corn cob-based porous carbon was studied by using corn cob-based porous carbon as adsorbent.The effect of corn cob-based porous carbon,Rhodamine B initial concentration,adsorption time,pH value and temperature on adsorption efficiency were discussed.The optimal adsorption condition of corn cob-based porous carbon for the dye of Rhodamine B was studied,and the thermodynamic mechanism and kinetic mechanism of adsorption were studied,which provided a corresponding theoretical basis for the removal of Rhodamine B in wastewater.
