| 摘 要： | 采用KOH活化法制备了禾草沟煤基多孔碳,并用于吸附对硝基苯酚研究。考察了对硝基苯酚溶液初始浓度、吸附时间、吸附温度、多孔碳投放量、溶液pH值等因素对对硝基苯酚吸附量的影响。结果表明,该吸附是一个快速吸附过程;吸附量随溶液初始浓度的增加先快速增加后趋于平缓,随多孔碳投放量的增加而增加。在25℃、溶液的pH值为7时,吸附效果最佳。

| Abstract: | The coal-based activated carbon was prepared by KOH activation and used for the adsorption of p-nitrophenol.The effects of initial concentration of p-nitrophenol solution,adsorption time,adsorption temperature,dosage of porous carbon and pH value of nitrophenol solution on the equilibrium adsorption capacity of p-nitrophenol were investigated.The results show that the adsorption process reaches equilibrium quickly.The adsorption capacity increases with initial concentration of p-nitrophenol solution rapidly firstly and then slowes down,and increases with dosage of porous carbon.The adsorption effect is the best when the temperature is 25℃and the pH value of the solution is 7. |
