The research represented here is oriented towards developing a new approach to functionalise a surface of Magnetic Nanoparticles with Polypyrrole (MNPs-PPy). This development will then applied to remove 2,4 dinitrophenol (2,4-DNP) in aqueous solution. A various analytical technique such as Fourier Transform Infrared Spectroscopy (FTIR) analysis, Scanning Electron Microscope (SEM), X-ray Diffraction (XRD) was employed for complete characterisation of MNPs-PPy. FT-IR spectra have shown the peak of Fe-O at 580 cm-1 while; the SEM images illustrated the globular structure of the surface of MNPs-PPy. Also, XRD result has shown the MNPs-PPy is in the crystalline form. The ultimate aims would then be the optimisation of the superlative condition of several parameters such as effect pH, temperature and concentration, contact time, amount of adsorbent, interfering ions and reusability for the removal of (2,4-DNP) in an aqueous solution by MNPs-PPy. The optimum conditions were observed at pH 6, 318 K, 10 ppm of analyte, 75 minutes and 50 mg of adsorbents which shown 98.67 % removal of analyte.
