Polyetherimide nanofibres as sorbents for organochlorinated pesticides determination

Popis výsledku v původním jazyce

In the present work, electrospun polyetherimide (PEI) nanofibres were fixed on a steel wire solid phase microextraction (SPME) assembly. The basic properties of the prepared nanofibres were determined by thermogravimetry, differential scanning calorimetry, adsorption and SEM. The analytical performance of prepared PEI SPME fibres was compared with three commercially available SPME fibres – PDMS 7 µm / 100 µm and DVB/Carboxene/PDMS. As model water pollutants, persistent organochlorinated pesticides hexanchlorocyclohexanes (HCH) and chlorobenzenes (ClB) were chosen as model water pollutants. The fibres were compared in the headspace (HS) SPME mode of GC MS/MS instrumentation. The comparison omitted other method parameters and focused exclusively on the extraction time variability. Lab-made PEI SPME fibres showed significantly better response for the target compounds than the other tested fibres from industrial production. Based on the results, the extraction time could be shortened from 50 to 10 min, if PEI SPME fibres were used as a modification of existing analytical protocol.
