Abstract: In this paper,the extraction experiments have been carried out for phenolextracted with 1-octanolin dilute solution.The distribution coefficient and the CO2DCrvalue in residualphase were measured under a wide pH range and various initialphenolconcentrations in the aqueous phase,and the relationship between CO2DCr value and the solute in the residualphase was analyzed.Based on the extractability and the CO2DCr value,the solution with and acidic or neutralpH values was proposed as a suitable condition for phenolextracted by 1-octanol.Finally,the removalphenolwas successfully achieved from industrialeffluent by the extraction with 1-octanol.
