A multicolumn method for the estimation of the octanol-air partition coefficient (K(OA)) of semivolatile compounds is described. The method is based on the retention time of a compound on gas chromatographic columns of different selectivity and polarity. Log K(OA) values of polychlorinated biphenyls (PCB) were estimated with the novel multicolumn method. The results were in excellent agreement with previously published data using a generator column method. Therefore, we used our multicolumn method to estimate K(OA) for more than 100 PCB congeners.
描述了一种用于估算半挥发性化合物正辛醇 - 空气分配系数(K(OA))的多柱方法。该方法基于化合物在具有不同选择性和极性的气相色谱柱上的保留时间。使用这种新型多柱方法估算了多氯联苯(PCB)的log K(OA)值。结果与先前使用发生器柱法发表的数据高度吻合。因此,我们使用多柱方法估算了100多种PCB同系物的K(OA)。
