Abstract
Aluminum mesocellulous silica foam (Al-MCF) was synthesized by pH-adjusting with hydrothermal method. Nano cavities of Al-MCF were characterized with FTIR, XRD and TEM methods. BET was done with N2-adsorption experiments and is showed the surface area 665.56 m2/g. TEM of Al-MCF was shown the particles diameters are pH dependent. Al-MCF particles were use d for adsorption of indigo carmine dye from aqueous solution. The sorption kinetics was found to follow a pseudo-second order kinetic model. The thermodynamic parameters were evaluated. The adsorption of IC onto Al-MCF foam was exothermic and negative value of ΔG° confirms the spontaneous process.
