Adsorption performance of tetracycline with porous carbon: The adsorption kinetics and isotherms

摘要

In this work, porous carbon was prepared by the solid phase synthesis method, using phenolic resin as carbon precursor and F127 as the template. The performance of as-prepared porous carbon was investigated by adsorption of tetracycline. Results indicated that the dosage of porous carbon 0.2 g, the concentration of tetracycline 15 mg/L, and the adsorption rate could reach 78.05% under a temperature condition of 20 °C. The adsorption kinetic process well fitted the pseudo-second-order model, and the adsorption isotherm well obeyed the Langmuir and Freundich isotherm at a low temperature and it fitted Freundich isotherm at a high temperature more.
