Abstract
A rapid method for analysis of chlorophenol content in sediments was developed using ultrasonic solvent extraction followed by stir bar sorptive extraction. The sediment sample is extracted using methanol and dichloromethane (9:1) in an ultrasonic bath. The extract is then redissolved in water and phenolic compounds are derivatised using acetic acid anhydride. The derivates are preconcentrated on a stir bar coated with polydimethylsiloxane that is commercially available as Gerstel Twister which is then thermally desorbed and analysed by GC-MS. Method performance is illustrated and evaluated for the enrichment of up to 100 ng g−1 of selected chlorophenols in freshwater sediment samples. The method showed good linearity, recoveries and blank levels, as well as advantages such as sensitivity, simplicity, low cost and high feasibility.
