Abstract

Aim of this study was to investigate the use of modified and carbonized SorghumHull of two different pore sizes (150µm and 250µm 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 150µm and 250µm were at 40 th and 60 th minutes respectively (55.152mg/l and 55.196mg/l). Both pore sizes showed peak adsorption of Zn 2+ at various contact time as shown in table 1. Kinetic modelings of the results of Zn 2+ 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 150µm and 250µm were particle diffusion controlled.
