Abstract
Sorption ability of Prosopis Cineraria Leaf Ash (PCLA) was investigated for removal of cadmium (II) from aqueous solution. The effect of different factors such as sorbent dose (1-3 g/L), pH (4-10) and initial concentration of cadmium (20-100mg/L) was studied in batch experiments. The experimental equilibria data were analyzed by Freundlich, Langmuir, Temkin and Brunauer-Emmett-Teller isotherm models. The Freundlich isotherm model provided a best fit with the equilibrium sorption data. Using Langmuir isotherm model the calculated maximum binding capacity was 24.6 mg of cadmium (II) per gram of PCLA. The maximum percentage of removed cadmium was 96% at pH of 7, with 3 g/L PCLA from solution containing 20 mg/L of Cd (II).
