Abstract: The absorption experiments of activated carbon on volatile phenol were carried out in different adsorbent dosages, pH values, adsorbent durations, temperatures, and initial concentrations, based on concentration measurement of volatile phenol in water. The adsorption characteristics of activated carbon on volatile phenol are analyzed, and the parameters obtained will provide a guidance for the design of sewage treatment with volatile phenol. The results show that the absorption reaches the maximum point of 96.04% when the temperature is 12℃, the adsorption time 20min, and activated carbon dosage 0.7g/50mL. The removal effect of volatile phenol under low initial concentration is better than under high initial concentration. The absorption isotherm of activated carbon on volatile phenol is consistent with the results of Freundlich.
