Bagasse fly ash (BFA) a sugar industry waste had been collected and converted to zeolitic material (MZBFA) by combined conventional and microwave reflux method. The synthesized sorbent has been characterized using various techniques such as FTIR, XRD, and SEM. BFA and MZBFA were used for the removal of phosphamidon (PSM), an organophosphorus pesticide from aqueous solution. The PSM sorption capacities of MZBFA and BFA were determined by batch sorption technique. Langmuir, Freundlich, Dubinin Redushkwich, and Temkin isotherms were estimated for the sorption nature and efficiency of sorbents. The sorption kinetics is better reflected by pseudo second order model and thermodynamics parameters exhibited specified endothermic nature of sorption. The overall sorption was approximated well by film diffusion at lower concentrations and pore diffusion at higher concentrations simultaneously. From the results, it was observed that MZBFA exhibited higher removal capacity than BFA. © 2013 American Institute of Chemical Engineers Environ Prog, 33: 114–122, 2014
