IR, XRD and SEM studies on the mechanism of adsorption of dyes and phenols by coir pith carbon from aqueous phase

Adsorption interactions of dye, phenol and chlorophenol onto coir pith carbon from aqueous solution were investigated using FT-IR Spectroscopy, Scanning Electron Microscopy (SEM), and X-ray diffraction techniques. IR studies revealed the participation of some of the surface functional groups in the adsorption mechanism, SEM revealed the morphological observations of the unloaded adsorbent and thereby changes in the adsorbed carbon. X-ray diffraction studies exhibited a decrease in crystalline nature of the loaded adsorbent compared with unloaded adsorbent.
