Özet: Polycylic aromatic hydrocarbons negative effects are identified by various studies. Pre-processing methods to increase analysis and pre-analysis concentration of PAHs have great importance, especially in drinking water. In this study, in drinking water, EPA 550.1 method used for analyis of polycylic aromatic hydrocarbons in drinking water is aimed to reduce the amount and time by performing the amount of chemical and analysis time. According to recovery and repeatability parameters, results are obtained with evaluation compared with values in EPA method 550.1. Using a total of 70 ml chemical modified by method for six PAH parameters, the percentage recovery results are as follows; flour anthems %99,5, Benzo(b)flouranthene %90,5, Benzo(k)flouranthene %84,8, Benzo(a)pyrene %91,1, Benzo(g,h,i )perylene 75,9 and Indeno(1,2,3-c,d)pyrene % 79,1.  Another concept that forms the basis of the SPE method, relative standard deviation of the percentage results for the same 6 PAH parameter are as follows; flouranthene % 12,8, Benzo(b)flouranthene % 8,4, Benzo(k)flouranthene %8,5, Benzo(a)pyrene % 8,02, Benzo(g,h,i)perylene % 12,2 and Indeno(1,2,3-c,d)pyrene % 17,5. In the modified innovative methods, recovery and repeatability results are observed that analytically compatible to the values of the method EPA 550.1.
