Abstract

Abstract: The absorption of benzopyrene in octane solution by rosin starch ester was studied in this paper.Affect factors including temperature,contact time,initial concentration of benzopyrene and the degree of substitution (D_s) of the rosin starch ester were investigated.The thermodynamics and kinetics of the absorption process were also studied.The results showed that increasing the absorption temperature,the benzopyrene concentration,and the D_s of the adsorbent were beneficial to the adsorption process.Using rosin starch ester (D_s=0.12) as adsorbent,absorbing 120 min at 50℃ in 10 mg/L benzopyrene,the absorption capacity of benzopyrene reached to 20.76 μg/g.The measured results were fitted with the Langmuir isotherm better.Thermodynamic parameters ΔG^Ø,ΔH^Ø and ΔS^Ø indicated that the adsorption process was spontaneous and endothermic.Analysis of the kinetic data suggested the pseudo second order kinetic model was suitable for describing the adsorption process.

Key words: rosin starch ester, benzopyrene, absorption process
