Abstract

Adsorption of zinc (Zn), cadmium (Cd), and nickel (Ni) from aqueous solutions by corncob (CC) and granular activated carbon prepared from corncob (GACC) were carried out. Synthetic solutions of Cd, Ni, and Zn at 3.0 ppm each were used to perform the adsorption process. A batch pattern was used to determine the kinetics as well as the adsorption isotherm parameters. The obtained results using either both the CC and GACC separately were found to be matched with the Langmuir isotherm model. Furthermore, the breakthrough study was conducted using GACC. The overall results indicated that the breakthrough curve for Cd, Ni, and Zn is the reverse of their adsorption, as demonstrated by R2 and kinetic constant (K) values.
