FUNCTIONALIZED NOVEL NANO COMPOSITES IN NI(II) REMOVAL FROM AQUEOUS/ EFFLUENT MEDIA

Abstract

Nano hydroxy apatite -Azaridachtaindica nutshell composite material was prepared in,co-precipitation method. The product was characterized by FT-IR and Atomic Force microscopy. The Ni(II) removal capacity of the synthesized novel material is investigated by employing batch mode to verify the sorption efficiency under optimized conditions viz., 11 mg/L initial concentration of Ni(II), 21 minutes agitation time between sorbent and sorbate molecules and 50mg dosage of the nano composite. The results of the experiment registered a significant increase • in the sorption nature of nano hydroxy apatite composite of the chosen nutshell against the chemically modified Azaridachtaindica nut shell where 450 mg dosage is employed under similar operating conditions. The successfulness of the nano material in trapping Ni{II) ions is extended to field levels through the assessment of effluents collected from electroplating industry suggesting that nano composited biomass of Azaridachtaindica nut shell is an efficient bioaccumulant.
