The present study was undertaken to investigate the use of waste orange peel as an adsorbent for adsorption of Cu (II) from aqueous solution after effectively extraction of value added component pectin. Four parameters affecting adsorption were studied, are pH (2.6, 4.3, 5.2, 6.8, 7.6), contact time (20, 40, 60, 80, 100 min), initial concentration (100, 200, 400, 600, 800, 1000 ppm) and adsorbent dosage (0.1, 0.2, 0.4, 0.6, 0.8, 1.0 gm.). The optimized parameters for maximum adsorption capacity was found to be concentration of 100 ppm at pH 6 to 7, contact time 60 to 100 min and adsorbent dosage of 1 gm. for 20 ml copper solution for both adsorbents. Maximum % removal of Cu (II) for pectin extracted orange peel was found 80.95% while for fresh orange peel it is 87.30%. The kinetics study was done by fitting the equilibrium data to Langmuir, Freundlich and Tempkin adsorption isotherm. It was found that Langmuir isotherm fitted well and most appropriate to describe adsorption kinetics. The adsorption of Cu (II) for both adsorbents follows pseudo second order kinetics and rate of adsorption is controlled by film diffusion.
