For the analysis of water for trace organics procedure of sample treatment to extract and concentrate the organics with XAD-2 resin was studied. At the levels of 10 ppb and 20 ppt the extraction and the concentration method were tested for 60 organic compounds including polycyclic aromatics, n-alkanes, phthalates, chlorinated benzenes, phenols, fatty acids, fatty acid methylesters, and steroids possibly found in surface waters. To 5 1 purified distilled water, 50 μg or 100 ng of each compound was added. After mixing the solution was passed through the XAD-2 resin column. The absorbed. organics were eluted from the resin with 100 ml diethylether and then the eluate was concentrated to 1 ml in a Kuderna-Danish evaporator. In ppb levels the organics were determined by GC-FID method and their average recovery was 83%. In ppt levels the analysis was performed by mass fragmentography and average recovery was 86%. By this method polycyclic aromatics (acenaphthene, fluorene, phenanthrene, and chrysene) and n-alkanes (C15C24) were determined in tap water. In these determinations polycyclic aromatics were found in the range of 1 ppt to 10 ppt and n-alkanes in 3 ppt to 30 ppt.
