Kinetic Study for Removal of Cu+2 from Waste Water by Chemically Modified Bio-Adsorbents of Citrus Reticulata

Sonam Kumari

Abstract: A series of waste of kinnow bio-sorbents has been prepared by different chemical modifications for the removal of copper (II) adsorption from waste water. The different bio-sorbents and raw kinnow peels were examined with different parameters like influences of pH, contact time, initial copper concentration. The maximum adsorption capacity of copper was 1.22 mol/kg, using orange peel esterified by 0.6 mol/L citric acid at 80 C after 0.1 mol/L NaOH saponification. A comparison of different isotherm models revealed that the combination of Langmuir and Freundlich (LF) isotherm model fitted the experimental data best. Results indicate that the chemically modified kinnow peel can provide an efficient and cost effective technology for eliminating copper from aqueous solution.
