Abstract: The sorption of monocrotophos (MCP) from aqueous solution by native bagasse fly ash (BFA) and zeolitic material (MZBFA) synthesised by combined conventional and microwave reflux method was studied. These sorbents were characterised by XRF, PXRD, FTIR and SEM and were establish to have improved morphology with new crystalline phases. Batch sorption experiments for the removal of MCP by BFA and MZBFA were carried out to evaluate isotherm capacity and kinetics of sorption processes. The isotherm data proved to fit the Langmuir isotherm than that of Freundlich, Temkin and Dubinin-Radushkevich isotherms. The highest sorption capacity, calculated through the values of the isotherm constant Kf, was obtained for MZBFA. The kinetics data proved a closer fit to the pseudo-second order model. The kinetics data of intra particle diffusion confirmed that the sorption rate was controlled by film diffusion followed by pore diffusion.
