Publisher's Synopsis
This book describes adsorption of cupric ions on Phoenix Dactylifera L. leaves is described. The adsorption phenomena is found to be dependent on pH, adsorbent dose, initial concentration, temperature and agitation time. Further this process was evaluated by adsorption isotherms namely langmuir, Fruendlich, Temkin, Hasley, Jonovaic and so. Kinetic models pseudo first order, pseudo second order, Elovich, Intra-particle diffusion are also evaluated. The optimum conditions for cupric ion uptake were found to pH=1.5, adsorbent dose =0.2 gm, initial concentration= 10ppm, agitation time =30 minutes . The adsorption is best described by Temkin adsorption isotherm model and pseudo second order kinetic model. The maximum adsorption capacity was evaluated to be 2.48 mg/g.
