Abstract

A multiresidue method has been developed for identificationand quantitationof theherbicides most commonly used in cultivationof maize and grain,andof their transformation products, in soil samples. The analytes were isolated by soil column extraction (SCE)and the extracts were purified by useof a Carbograph-1 cartridge. Analysis was performed by liquid chromatography coupled with tandem mass spectrometric detection (LC-TISP-MS-MS) in negative-ion mode. To optimize the extraction conditions affecting the performanceof SCE, e.g. the extracting solvent used, temperature, extracting volume,and solvent flow rate, were Studied. To evaluate the matrix effect in SCE, recovery experiments were performed on soil samples, with different physicaland chemical characteristics, fortified with the 100 ng g(-1)of the target compounds. Recovery data were satisfactoryand the method detection limits were between 3and 100 ng g(-1), depending on the compound.
