Abstract

ABSTRACT: In the preparation of fluorescent carbon nanoparticles, formation of non-fluorescent carbon particles (CPs) as waste matter is indispensible. This work is introducing CPs as adsorbents for some toxic metal ions in aqueous medium. CPs were characterised and their particle size, surface area, porosity, morphology etc. were compared with their parent material (charcoal). The effects of the initial metal ion concentration, contact time and pH on adsorption were undertaken. Adsorption data were evaluated for Langmuir and Freundlich isotherm models. The adsorption capacities (mg/g) of Ni 2+, Pb 2+, Zn 2+, Co 2+, Cd 2+ and Cu 2+ were 85, 76, 75, 67, 58 and 46, respectively.
