Differential pulse voltammetric determination of methyl parathion based on multiwalled carbon nanotubes-poly(acrylamide) nanocomposite film modified electrode

► A sensitive electrochemical sensor for detecting methyl parathion in environmental samples. ► The preparation, characterization and application of this novel MWCNTs-PAAM nanocomposite. ► The MWCNTs-PAAM/GCE exhibited a high adsorption and strong affinity toward methyl parathion. ► Wide linear range and low detection limit of the proposed method for detecting methyl parathion.
