Effect of Impregnation of Activated Carbon with Selected Transition Metal Ions on Its Adsorption Properties and Pore Size

Abstract. Thanks to their vast surface area, activated carbons are materials of great interest. They used as adsorbents for both liquid- and gaseous impurities. To improve properties, impregnation with different substances is conducted. In this paper, such an was done using copper(II), manganese(II), silver(I), zinc(II) salts. The aim compare the inner structure impregnated carbon a non-impregnated one. It by Brunauer-Emmett-Teller (BET) adsorption-desorption isotherms that were plotted described. Lastly, pore size volume determined Barrett-Joyner-Halenda (BJH) method. results show presence salts helped develop mesoporous resulted in increase area sorbents, while silver(I) decreased it.
