The dynamic adsorption experiment of 2,4,6-trichlorophenol (TCP) to the modified activated carbon (MAC) was studied.The experimental results show that the dynamic adsorption effect of MAC for 2,4,6-TCP is favorable, and the penetrative point is 33h, the balance point is 99h. In addition, Yoon-Nelson model can accurately predict the penetration characteristics of 2,4,6-TCP solution on the modified activated carbon column, where ln[Ci/C0-Ci] and t keep a good linear relationship, and the correlation coefficient R2= 0.9727. Time t of 50% penetration concentration, penetration point t1 ,and balance point t2 calculated by Yoon-Nelson model fit with the experimental datas well. |
