Pressurised solvent extraction for organotin speciation in vegetable matrices
Résumé
The evaluation and optimization of a specific procedure based on pressurized solvent extraction (PSE) that is suitable for monitoring organotin content in vegetables was reported. In ASE, solvents were used at elevated temperatures and pressures to increase the rate and efficiency of the extraction process. The influence of the pressure and the temperature of the PSE on the quantitativity of the process and on species preservation was evaluated using the experimental design methodology. COmparison with SLE comfirmed that PSE is an interesting tool for vegetable analysis considering the satisfactory OTC preservation and repeatability obtained for a relatively short extraction duration.
