Evaluation of an on-line coupled continuous flow liquid membrane extraction and precolumn system as trace enrichment technique by liquid chromatographic determination of bisphenol A

Extraction Techniques for Isolation, Purification and Preconcentration of Bisphenols and Alkylphenols from Environmental and Food Samples

“…For this purpose the most often used methods are liquid-liquid extraction [20][21][22], Soxhlet extraction [3,23], solid phase extraction [6,22,, membrane extraction [45][46][47], accelerated solvent extraction [7,13,[48][49][50][51][52][53][54], ultrasonic assisted extraction [32,[55][56][57][58], microwave assisted extraction [59][60][61], stir-bar sorptive extraction [4,[62][63][64][65][66][67][68][69], matrix solid phase dispersion [70][71][72][73][74] …”

“…Bisphenol A was found only in one sample (municipal sewage effluent) at concentration 280 ng/L [46]. Dȃas and Hamdaoui developed extraction methods via emulsion liquid membrane for the isolation of bisphenol A from aqueous samples.…”

Application of Molecular Imprinted Polymers for Selective Solid Phase Extraction of Bisphenol A

“…For this purposes, the various types of extraction methods such as solid phase extraction (SPE) [20,27,[29][30][31][32][33], liquid-liquid extraction (LLE), accelerated solvent extraction (ASE) [34] as well as membrane extraction (ME) [35,36] have been widely applied. In many cases, the techniques such as LLE, ASE, and ME made possible an efficient isolation of studied analyte, whereas, for preconcentration step, a using of subsequent solid phase extraction cartridges was necessary to be performed additionally.…”

Ανάπτυξη Μεθόδων Προσδιορισμού Ενώσεων Που Προκαλούν Ορμονικές Διαταραχές Με Υγροχρωματογραφία - Φασματομετρία Μαζών

“…Για τον προσδιορισμό της ΒΡΑ έχουν εφαρμοστεί κυρίως οι τεχνικές GC-ΜS [28, 31, 40, 184-186, 199, 200], HPLC-FLD [30,35,181,182,187,188,190,[192][193][194], LC-MS [29,33,36,165,195,202] και LC-MS/MS [38,189,191,198,201]. Ωστόσο, υπάρχουν αναφορές προσδιορισμού και με υγροχρωματογραφία συζευγμένη με ανιχνευτή συστοιχίας φωτοδιόδων ΗPLC-DAD [183,197] και με ηλεκτροχημικό ανιχνευτή [41,196], καθώς και με ανοσοχημικές τεχνικές [34,37].…”
