Abstract:
Objective To explore the determination of dioxin in wastewater samples pretreated by solid phase microextraction(SPME). Methods The wasterwater samples were purified and enriched by SPME, then were determined with HRGC-HRMS for the concentration of dioxin in wastewater samples. Results The most suitable conditions of the pretreatment were 30 min microextraction at 45 ℃. The detection limit was 0.05 pg/?l. RSD was lower than 10%. The recovery rates were 99%-102%. The concentration of total dioxins in wastewater sample was 0.78 pg/?l. Conclusion The method of the determination of dioxins in wastewater by SPME was simple and quick, and presented a broad prospects for application.
