고성능 액체 크로마토그래피의 간접 분광광도법에 의한 THM과 PCB의 분석 = Analysis of THMs and PCBs by Indirect Photometric Method in High Performance Liquid Chromatography

다국어 초록 (Multilingual 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.
