%X A novel method for the determination of soil organic carbon adsorption coefficients (K_OC) of pollutants was established using soil column liquid chromatography with stepwise adsorption. With this method the adsorption amount of samples at various concentrations on soil can be obtained in a single experiment. The values of K_OC can be calculated through adsorption isotherms. The soil column can be used without change or desorption throughout the whole experiment. This method leads to a shorter experimental duration, simplified experimental procedure and experimental error reduction. The values of log K_OC for tebuconazole, azinphos-methyl, diuron, atrazine, prometryn, phenol and naphthalene on the European reference soil of 3~# were measured to be 2.70, 2.87, 2.47, 2.26, 3.09, 1.51 and 2.77, respectively, which are consistent with the values reported in the literature.
