| 摘 要： | 通过对2－6环多环芳烃（PAHs)气相色谱保留时间（RGC）与HPLC保留值及与辛醇／水分配系数（KOW）对应关系的研究，发现RGC与HPLC保留值主KOW间存在明显的线性相关关系，建立了RGC与KOW间的一元回归方程，并对包括EPA16种优先控制的PAHs在内的33种多环芳烃化合物的KOW值进行估算，估算值的相对误差为0．10％－12．10％，平均值为4．51％。

| Abstract: | The study on the relationship between retention time(R GC)of gas chromatography and the octanol/water partition coefficients of polycyclic aromatic hydrocarbons(PAHs)with two to six rings indicates that the significant correlation is present.The octanol/water partition coefficients of thirty-three PAHs,include sixteen priority PAHs recommended by EPA,have been estimated using the unitary regression equation established on the basis of correlation analysis.The result of error analysis shows that it is a convenient method for estimating the octanol/water partition coefficients of PAHs.While,the range of relative error of the estimation is from 0.10% to 12.10% with a ave- vage of 4.51%. |
