| Abstract | Adsorption and desorption characteristics of some herbicides (CPA, MCPA and 2,4,5-T) from aqueous solution onto the active carbon materials (GAC, F-400) were studied. Adsorption equilibrium capacities of the herbicides increased with decreasing pH of the solution. Adsorption equilibrium isotherms can be represented by the Sips equation. Kinetic parameters were measured in a batch adsorber to analyze the adsorption rates of the herbicides. The internal diffusion coefficients were determined by comparing the experimental concentration curves with those predicted from the surface diffusion model and the pore diffusion model. The adsorption model based on the linear driving force approximation (LDFA) was used for simulating the adsorption behavior of the herbicides in a fixed bed adsorber. Over ninety five percent desorption of the herbicides can be obtained using distilled water. |
