Abstract

Iminodiacetic acid supported montmorillonite adsorbent was used for adsorptive removal of methylene blue dye in aqueous solution. Brunauer-Emmett-Teller (BET) isotherms, X-ray powder diffraction (XRD), Fourier transform infrared (FT-IR) spectrometer, and Scanning electron microscope (SEM) were used to characterize the physico-chemical properties of the adsorbents.  Iminodiacetic acid supported montmorillonite (MMT-IDA) adsorption capacity was found higher than montmorillonite (MMT) towards MB dye. Adsorption isotherm of the MMT-IDA was well fitted by the Langmuir model, with maximum adsorption capacity of 27.47 mg/g. The adsorption process was spontaneous exothermic, and kinetically fitted to pseudo-second order kinetic model. Thus, the obtained results encourage the use synthesis of iodate composite in the development of low-cost and effective adsorbent to remove MB present in industrial effluents.
