The present study deals with the adsorption of Cu (II), Fe (II) and Zn (II) onto Deodar leaves under different process conditions. The adsorption study was carried out by batch operation taking contact time, pH, adsorbent dose, initial concentration of metal ions in synthetic waste water and temperature. The percentage removal recorded for Cu (II) Fe (II) and Zn (II) are 75.42, 64.76 and 41.77 respectively after 25minutes at pH5 and 170 rpm. All these cations exhibit maximum removal efficiency at optimized conditions such as high pH, high dose of adsorbent and low initial concentration of metal ions. The equilibrium adsorption capacity of adsorbent used for these metal ions is measured and extrapolated using linear Freundlich, Langmuir and Temkin isotherms. The experimental data are found to follow the order Langmuir>Freundlich>Temkin, indicating monolayer adsorption on a homogenous surface.
