A thin biofilm of chitosan as a sorptive phase in the rotating disk sorptive extraction of triclosan and methyl triclosan from water samples

Synthesis and evaluation of a chitosan nanomaterial as efficient sorbent for determination of fungicide residues in waters and wine by liquid chromatography high resolution mass spectrometry

“…11,12 The use of chitosan as analytical sorbent has been reported in water and food samples, under several conguration: i.e. disk sorptive extraction, 13 ultrasoundassisted magnetic solid phase extraction, 14 pipette tip-solid phase extraction, 15 and dispersive micro-solid phase extraction (D-m-SPE). 16 D-m-SPE consists in introducing a sorbent directly into a small sample volume.…”
