Abstract :

The present work explored the use of Egyptian rice straw, an agriculture waste that lead to a global warming problem through brown cloud, as a potential feedstock for the preparation of activated carbon with high surface area by chemical activation. Chemical activation of this precursor, using two different methods was adopted. One of these methods was carried out using H 2 SO 4 for carbonization while activation carried out using KOH and the other method include activation using KMNO 4 . The produced activated carbon was fully characterized considering its adsorption properties (surface area and pore volumes) as well as its chemical structure and morphology. Application of using the produced activated carbon and raw rice straw for removal of Ni was evaluated in a batch operation system. Studying of the operating conditions namely; effects of contact time, dosage of adsorbent, initial concentration as well as effect of pH were carried out. Also kinetics and isotherm study that describe the adsorption process are carried out.
