VALIDATION STUDIES ON ACTIVATED CARBON FIBER PASSIVE SAMPLER FOR PCDD/FS AND PCBS IN WATER

Chemosphere 239:124666(2020)
A characterization and validation study was conducted on activated carbon filters (ACF) to monitor for PCBs, polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) in water. The filters were characterized as having a specific surface area of ~2500 m2/g, which consisted of a homogeneous microporosity distribution and had balanced basic and acidic surface functional groups. The validity of using the ACF as solid-phase extraction and as passive sampler was evaluated by the percentage recovery (R %) of 13C12-labeled standards of PCDD/Fs and PCBs added in a known volume of water. When compared to the R% of liquid-liquid extraction, the authors suggest the method has a better reproducibility of results and is capable of satisfying the extraction requirements of EPA reference methods.
