Abstract A method for determination of four chlorobenzene compounds in water and wastewater by solid phase extraction with FID-GC detection was investigated.The extraction efficiency of four chlorobenzene compounds on Sdex C18 column,Sep-Park Vac Silica column,Bond Elut CARBON column,Bond Elut SI column and Bond Elut PLEXA column was compared,and the Sdex C18 column had the best recovery.The method for solid phase extraction was further systemically studied.Methanol of 4.0 mL is used as eluting solvent,and the adsorption eluent can not be concentrated by nitrogen blowing;the breakthrough volume of most compounds is above 1.0 L,but that of chlorobenzene is 300 mL.It shows that the Sdex C18 column has a strong adsorption of dichlorobenzene and trichlorobenzene.Under the optimized conditions,the linear rang was 20.0-400μg/L,and the detection limit was 0.383-0.635μg/L.It fully meets the requirements of daily environmental monitoring and analysis.
