Abstract


The low cost adsorbent namely, a Cassia Siamea (CS), Albizia Labbeck (AL), Nerium Indicum (NI), Durauta Erecta (DE), and Potato Husk (PH) have been tested for the effectiveness on removal of copper (Cu (II)) by an adsorption technique. The various parameters such as contact time and temperature were applied for the study. The equilibrium was attained within 50 min, the adsorption was studied in the pH 5, adsorbate concentration 150 ppm and amount of adsorbent 0.2 gm. Adsorption was carried out at different temperature in the range of 293 to 333 . . It was observed that the adsorption increase with increasing in time. The kinetic data was fitted using both Pseudo first order model and second order model, Langmuir and Freundlich models were often used to describe equilibrium adsorption isotherms and the thermodynamic parameters, change in enthalpy (?H) (KJ/mol) and change in entropy (?S) (J/mol) which related to the Gibbs free energy (?G).
