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 g1. 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 DG8 confirms the spontaneous process.
