“…Entre estas técnicas pode-se destacar: o particionamento de solventes (extração líquido-líquido), extração sólido-líquido (Solid Liquid Extration -SLE) [96,[100][101][102][103] , extração assistida por micro-ondas (Microwave Assisted Extraction -MAE) [104][105][106] , extração em fase sólida (Solid-Phase Extraction -SPE) [106][107][108][109][110][111] , microextração em fase sólida (Solid-Phase Microextraction -SPME) [104,[112][113][114] , dispersão da matriz em fase sólida (Matrix Solid-Phase tro importante que deve ser considerado, pois, dependendo do tipo de detector a ser utilizado, os LMR estabelecidos podem não ser atingidos.…”

“…In recent years, many new techniques, for example accelerated solvent extraction (ASE) [18], microwaveassisted extraction (MAE) [17,18], and supercritical-fluid extraction (SFE) [19] have been used for analysis of OCPs in many sample matrices. Compared with traditional methods these extraction techniques have advantages such as reduction of the volume of extraction solvents and time of analysis, a high level of automation, and improvement of the reproducibility of compound recovery [19].…”

“…Mastovska et al [16] developed a method that used extraction by shaking in a separating funnel and dispersive solid-phase extraction combined with GC-TOF-MS and UPLC-MS-MS for analysis of pesticide multiresidues in cereal grain. A method for analysis of six OCPs in cereals using dynamic microwave-assisted extraction coupled with online solid-phase extraction then high-performance liquid chromatography has been reported [17]. Usually, however, these methods are costly, because of the large amounts of solvents and other expensive consumables used, hazardous, and the level of automation is low, because of the conventional extraction procedures used.…”
