Removal of Cobalt Metal Ion from Aqueous Solution using Punica granatum Stem Powder as Biosorbent

Abstract

Abstract: Natural agricultural solid waste material is very cost effective for synthesizing adsorbents utilized in removal of heavy metal ion from economic and noneconomic waste waters which are numerously exploded in environmental soil and water resources. Punica grantanum (pomegranate) stem powder (PGSP) was synthesized into nanoparticle size and practiced in removal of cobalt metal ions. Adsorbent was synthesized in greener manner in aqueous medium. Batch adsorption study was carried with parameters including effect of pH (pH 4, 73.13%), adsorbent dose (200mg, 70.80%), concentration of metal ion (200 ppm, 81.56%) and effect of temperature (30℃, 71.56%). Characterization study of PGSP before cobalt metal ion adsorption and after cobalt metal ion adsorption was conducted including scanning electron microscopy, transmission electron microscopy, X- ray diffraction analysis, fourier transform infrared spectroscopy, ultra violet visible spectroscopy and elemental detection analysis.
