Abstract: Aim of this study was to investigate the use of modified and carbonized Sorghum Hull of two different pore sizes 150m and 250m in the removal of Cadmium II ion from aqueous solution. The effect of contact time 20, 40, 60, 80 and 100 minutes were investigated, reported and analysed accordingly. The maximum adsorption for 150m and 250m were at 80th and 40th minutes, respectively 54.895mg-l and 58.874mg-l. Kinetic modeling of the results of Cadmium II ion of both pore sizes were also investigated, reported and analysed. These results showed that Pseudo second order kinetic model best described the sorption process. The Mechanism of sorption showed that CMSH 150m and 250m, respectively were particle diffusion controlled. This will serve as parameters to consider in the design of treatment plants for heavy metal detoxification using biosorbents of different pore sizes. This study is one of the very few studies which have investigated on Sorghum Hull and its use in the adsorption of Cadmium II ion from aqueous solution synthetic wastewater. It documents the kinetics and mechanism of adsorption process; design pattern for wastewater treatment plant construction using a novel adsorbent.
