| description | <p>Tannins extracted from the mangrove barks of Rhizophora apiculata species were modified into tannins-based adsorbent (TBA) by using formaldehyde in the basic solution of ammonia. The produced adsorbent showed high efficiency in removal of Cu2+ from the aqueous solution. Effect of adsorption parameters like initial adsorption pH, initial desorption pH and initial Cu2+ concentration were studied in batch experiments. The optimum adsorption pH of Cu2+ was at pH 7.0 with an adsorption percentage of 96.20%. Meanwhile, 82.68% of Cu2+ was desorbed from the loaded TBA at the initial pH of 4.0, which was the optimum desorption pH. Non-linear regression analysis was conducted to determine the fitness of Langmuir, Freundlich, Sips and Dubinin-Raduskhevich (D-R) isotherms to the experimental data at equilibrium. TBA showed high monolayer adsorption capacity of 17.41 mg of Cu2+/gram of adsorbent. Mean energy of adsorption, E calculated from D-R isotherm showed that adsorption of Cu2+ on TBA followed ion-exchange mechanism.</p> |
