Abstract

MCM-41 functionalized with aminopropyl and vinyl group were studied as potential adsorbent for removal of Cu (II). Materials were characterized by using XRD, FT-IR and TGA. Standard structure of MCM-41 at [100] planar was retained after functionalization. Batch adsorption study was carried out to determine effect of variable parameters (i.e. initial concentration, pH and adsorbent dosage) towards adsorption of Cu (II) from aqueous solution. Cu (II) adsorption was found to be dependent on variable parameters. Adsorption of Cu (II) was also found to fit Langmuir isothermal compared to Freundlich isothermal model. Regeneration of adsorbent by using disodium EDTA and acid base treatment showed that percentage of metal recovery is higher when using disodium EDTA.
