摘要

Adsorption and desorption characteristics of 2,4-dichlorophenoxybutyric acid (2,4-DB) from aqueous solution on bamboo activated carbon (BAC) were studied in a fixed bed adsorber. The adsorption equilibrium capacity of 2,4-DB on BAC increased with decreasing initial pH of the solution and with a maximum adsorption capacity of 1.61 mol/kg. The adsorption rate of 2,4-DB on BAC could be best fitted by the pseudo first-order model. The adsorption model based on the linear driving force approximation (LDFA) was used for simulating the adsorption behavior of the 2,4-DB in a fixed bed. More than 95% desorption of 2,4-DB was obtained using distilled water.
