Abstract :
The adsorption of diesel oil in seawater on biodegradable adsorbing material and the influencing factors such as salinity, pH and temperature were studied. Results showed the adsorption of diesel fitted the second-order reaction model, and the saturated adsorption capability was 6.69g/g which can be reached in 10-20min. The diesel oil removal efficiency increased with the increment of salinity and pH of seawater, and decreased when the environmental temperature rose. The adsorption isotherms could be described as Freundlich´s and BET equation.
