Evaluation of an Spme and Gc–ms Method for Analysis of Fluazifop in Water
نویسنده
چکیده
Combination of solid-phase microextraction with gas chromatography enables rapid, repeated analysis of organic compounds in water. Fluazifop-p-butyl (FPB) (propanoic acid 2-[4-[[5-(trifluoromethyl)-2-pyridinyl]oxy]phenoxy] butyl ester) is the active substance in the herbicide Fusilade. Samples of distilled water were spiked with FPB in the laboratory and the analyte was isolated from the water by solid-phase microextraction on a polydimethylsiloxane fibre. Optimum conditions (time, temperature, stirring, pH) were found for extraction of FPB from the water matrix. Limit of detection, standard curve calibration, and range of concentration in which detector response was linear were determined. Suitable conditions for chromatographic analysis were also determined.

A fiber coating from polyaniline (PANI) was electrochemically prepared and employed for Solid phase micreoextraction (SPME). The PANI film was directly electrodeposited on the platinum wire surface using cyclic voltametry (CV) technique. The same method was applied for the preparation of SPME fiber coated by polyaniline multiwalled carbon nanotubes (PANI/MWCNTs) composite. The concentration of ...
