Abstract: This research describes the development of a new design of electrospun nanosorbent, polystyrene/methacrylic acid nanofibers (PS/MAA NFs), for the extraction and preconcentration of Methyl green (MG) from aqueous samples via solid phase extraction (SPE). The experimental parameters affecting the SPE extraction efficiency including sample flow rate through the sorbent, ionic strength and pH of the sample solution, weight of sorbent, volume and type of eluent were investigated, and optimized. Under the optimum conditions (40 ml of 1 mg/L MG, pH: 5, sample flow rate: 2 ml/min, 0.1 g PS/MAA NFs and eluting solvent: 3 ml MeOH), the calibration curve was linear in the MG concentration range of 25–1,000 μg/L. The limit of detection and enhancement factor of the proposed method, for extraction from 40 ml sample solution, were obtained as 10 μg/L and 8.3, respectively. MG dye was extracted from different real samples (urban, mineral and river waters) using the proposed adsorbent and the results showed that PS/MAA NFs were suitable for preconcentration and determination of trace amount of methyl green in wastewater samples.
