Analytical application of MIL-53 (Al) for the extraction of pesticides from fruit juices following their preconcentration through dispersive liquid-liquid microextraction

Extraction of diazinon, haloxyfop-R-methyl, hexaconazole, diniconazole, and triticonazole in cheese samples using a ferrofluid based liquid phase extraction method prior to gas chromatography

“…S1 †), the method efficacy increases till 1 min and then remains nearly constant. It can be concluded that 1 min was sufficient for the effective extraction of the analytes 25 and selected for the next experiments.…”

“…It can be related to the hydrolysis of the analytes at high concentrations of TCA. 25 As a result, 15% w/v of TCA solution was utilized in the following experiments.…”

“…The studied pesticides in this study are the common pesticides used by Iranian farmers. 25 They have long chemical and photochemical half-lives and simply accumulate in various products. The extracted and preconcentrated analytes were determined using a GC-flame ionization detector (FID).…”

Development of In-Needle SPME Devices for Microextraction Applied to the Quantification of Pesticides in Agricultural Water

“…The emergence of green analytical chemistry has led to the development of new extraction methods that have lower human and environmental impacts [ 8 , 9 , 10 ]. Besides liquid–liquid extraction, which is the conventional procedure used for the isolation of trace pesticides from aqueous samples [ 11 ], several other techniques have also been used, including solid-phase extraction, dispersive solid-phase extraction [ 12 ], matrix solid-phase extraction [ 13 , 14 ], supported liquid extraction [ 15 ], and dispersive liquid–liquid microextraction [ 16 ]. Additionally, QuEChERS (quick, easy, cheap, effective, rugged, and safe) is a widely used analytical approach that simplifies the analysis of multiple pesticide residues in fruit, vegetables, cereals, and processed food [ 17 ].…”
