Abstract

Aim of this study was to investigate the use of modified and carbonized SorghumHull of two different pore sizes 150 m and 250 m meshes inthe removal of Zinc II ion from aqueous solution The effect of contact time 20 40 60 80 and 100 minuteswere investigated and reported The maximum adsorption for 150 m and 250 m were at 40th and 60th minutes respectively 55 152mg l and 55 196mg l Both pore sizes showed peak adsorption of Zn2 at various contact time as shown in table 1 Kinetic modelings of the results of Zn2 of both pore sizes were also investigated These results showed that Pseudo second order kinetic model best describes the process and the Mechanism of adsorption show that 150 m and 250 m were particle diffusion controlled
