介绍了动态耦合柱液相色谱法测定多环芳烃在水中溶解度的方法。DCCLC技术是一种非常快速、精确和准确的方法，用于测定微溶有机化合物的水溶解度行为。多环芳烃的水溶解度与溶解度参数的计算结果吻合较好.三角洲Hs，与以前在文献中报道的值有助于确认这种方法的有效性。在所有情况下，在恒定温度下所产生的PAH溶液的重复溶解度测量值均优于± 3%，并且在大多数情况下优于± 1%。缺乏一个合适的物理参数，准确地外推PAH的溶解度进一步提高DCCLC方法的实用性。
The dynamic coupled column liquid chromatographic (DCCLC) method for determining the solubility of polycyclic aromatic hydrocarbons (PAH) in water is described. The DCCLC technique is a very rapid, precise, and accurate method for determining the aqueous solubility behavior of sparingly soluble organic compounds. The agreement of PAH aqueous solubilities and calculated solubility parameters, such as ..delta..Hs, with values that have been previously reported in the literature helps to confirm the validity of this approach. In all cases replicate solubility measurements of the generated PAH solutions at constant temperature were better than +- 3 percent and in most cases better than +- 1%. The lack of an appropriate physical parameter for accurately extrapolating PAH solubilities further enhances the utility of DCCLC method.
