| 英文摘要 | the capacity factors of a series of hydrophobic organic compounds (hocs) were measured in soil leaching column chromatography (slcc) on a soil column, and in reversed-phase liquid chromatography on a c-18 column with different volumetric fractions (phi) of methanol in methanol-water mixtures. a general equation of linear solvation energy relationships, log(xyz) = xyz(0) + mv(1)/100 + spi* + bbeta(m) + aalpha(m), was applied to analyze capacity factors (k'), soil organic partition coefficients (k-oc) and octanol-water partition coefficients (p). the analyses exhibited high accuracy. the chief solute factors that control log k-oc, log p, and log k' (on soil and on c-18) are the solute size (v-1/100) and hydrogen-bond basicity (beta(m)). less important solute factors are the dipolarity/polarizability (pi*) and hydrogen-bond acidity (alpha(m)). log k' on soil and log k-oc have similar signs in four fitting coefficients (m, s, b and a) and similar ratios (m:s:b:a), while log k' on c-18 and log p have similar signs in coefficients (m, s, b and a) and similar ratios (m:s:b:a). consequently, log k' values on c-18 have good correlations with log p (r > 0.97), while log k' values on soil have good correlations with log k-oc (r > 0.98). two k-oc estimation methods were developed, one through solute solvatochromic parameters, and the other through correlations with k' on soil. for hocs, a linear relationship between logarithmic capacity factor and methanol composition in methanol-water mixtures could also be derived in slcc.
