Application of MXene as a new generation of highly conductive coating materials for electromembrane-surrounded solid-phase microextraction

Abstract For the first time, highly conductive thickly layered two-dimensional titanium carbide (MXene) was applied as a new coating agent for electromembrane-surrounded solid-phase microextraction (SPME) of triadimenol and iprodione two model analytes. Preparation desired coated electrode carried out using electrophoretic deposition MXene on surface platinum electrode. Characterization prepared conducted scanning electron microscopy energy-dispersive X-ray spectroscopy. The located inside hollow fiber membrane impregnated by 2-nitrophenyl octyl ether supported liquid (SLM), while an aqueous solution injected lumen. Separation quantification analytes were gas chromatography instrument equipped with mass spectrometric detection. effective parameters procedure comprising pHs sample acceptor phase, composition SLM, extraction voltage optimized one-variable at-a-time method. Under optimal conditions, calibration curves linear ( R 2 > 0.9973) in range 0.3–250.0 0.5–250.0 ng mL −1 iprodione, respectively. limit detections determined to be 0.10 0.15 Repeatability reproducibility method evaluated calculation intra-day inter-day relative standard deviations (%). applicability quantitative analysis environmental water samples.
