| 英文摘要 | to avoid the limitation of the widely used prediction methods of soil organic carbon partition coefficients (k-oc) from hydrophobic parameters, e.g., the n-octanol/water partition coefficients (k-ow) and the reversed phase high performance liquid chromatographic (rp-hplc) retention factors, the soil column liquid chromatographic (sclc) method was developed for k-oc prediction. the real soils were used as the packing materials of rp-hplc columns, and the correlations between the retention factors of organic compounds on soil columns (k(soil)) and k-oc measured by batch equilibrium method were studied. good correlations were achieved between k(soil) and k-oc for three types of soils with different properties. all the square of the correlation coefficients (r-2) of the linear regression between log k(soi) and log k-oc were higher than 0.89 with standard deviations of less than 0.21. in addition, the prediction of k-oc from k-ow and the rp-hplc retention factors on cyanopropyl (cn) stationary phase (k(cn)) was comparatively evaluated for the three types of soils. the results show that the prediction of k-oc from k(cn) and k-ow is only applicable to some specific types of soils. the results obtained in the present study proved that the sclc method is appropriate for the k-oc prediction for different types of soils, however the applicability of using hydrophobic parameters to predict k-oc largely depends on the properties of soil concerned.
