Abstract
THMs and PCBs were separated and analysed with elution on Novapak ODS or $\mu-Bondapak$ phenyl column by an eluent containing p-nitrophenol (p-NP). THMs studied were CHCl3, CHBrCl2, CHBr2Cl, and CHBr3, and PCBs used were Aroclor 1221, 1242, 1248, $\alpha-$ and $\beta-BHC.$ It was thought that the retention on the stationary phase and sensitivities of the samples are related to the interaction between the sample and stationary phase or p-NP. THMs were separated completely on the ODS column by elution with MeOH-water (30 : 70) containing $1.0{\times}10^{-4}$ M p-NP and some of PCBs were separated on the phenyl column by elution with $CH_3CN$-water(50 : 50) containing $1.0{\times}10^{-4}$ M p-NP. Detection limits of THMs were from $1.0{\times}10^{-4}$ g to $1.0{\times}10^{-6}$ g. Aroclors were $2{\times}10^{-6}$ g, and $\alpha-$ and $\beta-BHC$ were $2{\times}10^{-4}$ g and $1.0{\times}10^{-4}$ g respectively.
p-니트롤페놀을 용리액에 첨가하고 THM과 PCB를 Novapak ODS관과 $\mu-Bondapak$ 페닐관으로 용리시켜 분리 및 분석하였다. 사용한 THM은 $CHCl_3$,\;CHBr_2Cl$ 및 CHBr_3$였고, PCB는 Aroclor 1221, 1242, 1248, ${\alpha}-$ 및 ${\beta}$-BHC였다. THM과 PCB의 정지상에의 머무름과 검출감도는 시료와 정지상 또는 시료와 용리액에 첨가한 p-니트로페놀과의 상호작용에 의존되었다. THM은 $1.0{\times}10^{-4}$M p-니트로페놀을 용해시킨 메탄올-물(30:70) 용리액을 사용하여 ODS관으로, PCB는 아세트니트릴-물(50:50) 용리액을 사용하여 페닐관으로 용리시킴에 의하여 몇 가지를 분리 및 분석할 수 있었다. THM의 검출한계는 $1.0{\times}10^{-4}g$으로부터 $1.0{\times}10^{-6}g$였고, PCB 중 Aroclor들의 검출한계는 $2.0{\times}10^{-6}g$, {\alpha}-$와 ${\beta}$-BHC는 각각 $2.0{\times}10^{-4}g$과 $1.0{\times}10^{-4}g$였다.
