Özet: In the present study, we have used the waste leaves of Rhododendron arboreum as adsorbent for the removal of Pb2+ and Cd2+ ions from waste water. The adsorbent was characterized by means of FTIR and FESEM methods. The percentage adsorption has been achieved as 67.9 %, 58.9% and 98.8% for Pb2+ and 41%, 22.4% and 86.2% for Cd2+ ions at contact time 60 minutes, dosage 1g and pH 6, respectively. The equilibrium data of adsorption were tested with Langmuir,Freundlich isotherm models, Pseudo-first order and Pseudo-second order kinetic models.
