The separation and sample extraction methods of 19 polycyclic aromatic hydrocarbons (PAHs) in water samples were investigated by gas chromatography/mass spectrometry (GC/MS) and some extraction methods involved liquid-liquid extraction, disk extraction and solid-phase extraction methods. The separation of 19 PAHs was possible by partial variation of oven temperature of GC/MS in temperature range <TEX>$80{\sim}310^{\circ}C$</TEX>. Extraction procedures of PAHs in water samples were somewhat modified and compared as extraction recoveries and the simplicity of methods. Extraction recoveries of PAHs were 71.3~109.5% by liquid-liquid extraction method. By using disk extraction, good extraction recoveries (80.7~94.9%) were obtained in case of <TEX>$C_{18}$</TEX> disk extraction method by filtration. And extraction recoveries of PAHs by <TEX>$C_{18}$</TEX> solid-phase were in the range of 51.8~77.9%. Method detection limits (S/N
