| Abstract: | Objective ] The aim of the study was to use GAC （ Granular activated carbon） for adsorption treatment of wastewate containing 4- chlorophenol. Method ] The adsorption process of 4-chlorophenol in simulated wastewater by GAC was studied. Result ] Under 30℃ and the 150r/min of shaker speed, the time of the granular activated carbon on 4-chlorophenol adsorption equilibrium was 6 hours. The experimental data was regressed by langemuir and freundlich isotherm models . The adsorption behavior of granular activated carbon on 4-chlorophenol conformed to freundlich isotherm equation. The breakthrough curve of 4-chlorophenol through granular activated carbon fixed bed was measured at 30 ℃. The results showed that the granular activated carbon adsorption capacity at the penetration point was 37.8 mg/g carbon, only 0. 501 8 of the static adsorption capacity at the same conditions. Conclusion ] The GAC had very good performance in absorption of simulated wastewater with 4-chlorophenol. |
