Hydrothermal synthesis was carried out for synthesis of Zeolite W under the static conditions. The synthesize sample was characterized by X-ray diffraction (XRD), Scanning Electron Microscope-Energy Dispersive spectroscopy (SEM–EDAX) and Fourier Transform Infra Red (FTIR) spectrocopy. Zeolite W was used as an adsorbent for the adsorption of malathion from aqueous solution. Adsorption studies were performed in a batch system. The effects of various experimental parameters (contact time, solution pH, effect of temperature and adsorbent doses) on the adsorption efficiency of zeolite W against were investigated for malathion. Zeolite W also performed against malathion in acidic and basic condition but highest adsorption capacity observed at pH 7 (aqueous solution).
