Solid-phase extraction derivative aromatic compounds in water samples and determination of using GC-FID

A simple method to pre-concentrated derivative aromatic compounds on active carbon in column has been applied as stationary phase which is used to measure the concentration of derivative aromatic compounds in water samples by means of solid-phase extraction. To measure 250 cc water samples and 250mg active carbon could be applied. Next step is to measure the derivative aromatic compounds by injecting them to the gas chromatography with flame ionization. The advantages of applying gas chromatography-flame ionization detection (GC-FID) with SPE in presence Carbon active are high sensitivity, High speed transformation of aromatic compounds and improving ration standard for river waters with derivative aromatic compounds in the range of ppb or those with less than 10% of LOD. The quantity of extraction could be affected by sample's pH, amount of solvent, washing liquid type, solvent and flow rates of the sample solutions.
