An automatic method for the determination of organochlorine pesticides (OCPs) in water samples was developed. The analytes are preconcentrated onto a customized RP-C 18 column and subsequently eluted with 80 μl of ethyl acetate. Gas chromatography with electron capture detection is used for their separation and selective detection. Detection limits for 10 ml sample volumes range from...
In this study, a simple, rapid and efficient method, dispersive liquid–liquid microextraction (DLLME) combined gas chromatography–electron capture detection (GC–ECD), for the determination of chlorobenzenes (CBs) in water samples, has been described. This method involves the use of an appropriate mixture of extraction solvent (9.5μl chlorobenzene) and disperser solvent (0.50ml acetone) for the formation...
A novel method for the determination of organochlorine pesticides in water samples with extraction using cork fiber and analysis by gas chromatography with electron capture detector was developed. Also, the procedure to extract these pesticides with DVB/Car/PDMS fiber was optimized. The optimization of the variables involved in the extraction of organochlorine pesticides using the aforementioned fibers...
A novel sorbent based on a UVM-7 mesoporous silica doped with Ti has been synthesized and used for solid-phase extraction of several organophosphorus pesticides in environmental water samples followed by gas chromatography coupled to a nitrogen-phosphorus selective detector. Thus, mesoporous silica materials doped with Ti and Fe as well as immobilized cyclodextrin silica-based supports were prepared...
