with the continuous mining of heavy oil in domestic oilfield and shortage of water resources, the effective treatment and recycling of heavy oil wastewater are urgent. According to the characters of heavy oil wastewater, the kinetics of the sorption of humic acid onto five macro porous adsorption resins in aqueous solution was investigated in batch experiments. The experiments showed that the pseudo second-order equation could describe the sorption process of Ca2+ and Mg2+ in heavy oil wastewater. However, from the model we can conclude that the adsorption rate was controlled by film diffusion and particle diffusion simultaneously, but particle diffusion was the key step of the adsorption rate.
