Syzygium cumini leaf powder as low cost adsorbent to remove Fe (II) from aqueous solution

Syzygium cumini Leaf Powder (SCLP) was treated with nitric acid and used as a low cost, easily available and renewable biological adsorbent for the removal of Fe (II) from aqueous solution. Batch experiments were carried out for adsorption kinetics and isotherms. Operating variable studied were contact time, adsorbent dose, initial concentration of adsorbate, temperature and pH. Adsorption capacity seems to be enhanced by increasing temperature up to 40ºC and adsorbent dose. Equilibrium data were well represented by the Freundlich isotherm model for all tested adsorption systems. Beside these the Thermodynamic study has showed that the Fe (II) adsorption phenomenon onto SCLP was favorable and spontaneous
