Linear sorption isotherms were found for sorption of benzothiophene by no treatment and NaOAC-HOAC treatment sediments. The ediment treated by NaOAC-HOAC exhibited obviously larger Kp value for benzothiophene. The observed Koc value was basically consistent with the value predicted from the benzothiophene solubility in water. Nonlinear isotherms were observed for adsorption of benzothiophene on the sediments treated by H2O2 and could be described by the Freundlich equation.展开更多
文摘The sorption behavior of benzothiophene on marine sediments treated by different procedures was studied. Linear sorption isotherms were found for sorption of benzothiophene by no treatment and NaOAC-HOAC treatment sediments. The ediment treated by NaOAC-HOAC exhibited obviously larger Kp value for benzothiophene. The observed Koc value was basically consistent with the value predicted from the benzothiophene solubility in water. Nonlinear isotherms were observed for adsorption of benzothiophene on the sediments treated by H2O2 and could be described by the Freundlich equation.
