The adsorption performance of plant oil for phenol was studied by ultraviolet spectrophotometry.The effects of time,temperature,the mass concentration of phenol,the dosage of plant oil,and pH on the adsorption capacity of plant oil for phenol were investigated.The adsorption kinetics and thermodynamics of phenol onto plant oil were also discussed.The results show that the four influencing factors were in the following order of significance: the mass concentration of phenol> the dosage of plant oil> temperature> pH.The optimum adsorption conditions were the 3 g of plant oil,temperature of 20 ℃,pH of 6.2,and the mass concentration of phenol 20 mg/L.The adsorption capacity of plant oil for phenol was 0.07 mg/g.The adsorption of phenol onto plant oil obeyed Freundlich equation.
