Abstract: Adsorption interaction of acid azo dye sorption onto coal based sorbent and activated carbon form aqueous phase was investigated using IR, X-ray diffraction, and SEM techniques. IR studies revealed the participation of some of the surface functional groups in the adsorption interaction. X-ray diffraction studies exhibited the increase in crystalline nature of the loaded sorbents compared to the unloaded sorbents. SE micrograms revealed the morphological observations of the unloaded sorbents and thereby changes in the loaded sorbents indicating the participation of the porous network of the sorbents in the sorption interaction.
