Solid-phase extraction (SPE) was combined with dispersive liquid-liquid microextraction based on solidification of floating organic droplet (DLLME-SFO) as a pretreatment technique for the simultaneous analysis of 11 organochlorine pesticides (OCPs) and 5 polychlorinated biphenyls (PCBs) in fish tissue. Gas chromatography with electron capture detector was used for the identification and quantification...
A simple and rapid method applying acetonitrile extraction, dispersive-solid-phase extraction (d-SPE) cleanup, and dispersive liquid-liquid microextraction based on solidification of floating organic droplet (DLLME-SFO) was developed for determination of organochlorine pesticides in vegetables. In order to simplify operation, d-SPE cleanup was integrated to DLLME-SFO concentration procedure, and a...
