BIOSORPTIVE POTENTIALS OF UNMODIFIES, CHEMICALLY MODIFIED AND CARBONIZED SAWDUST FROM SOME WOODY MAYERIALS
Adsorption can be applied for solution containing low concentration of heavy metals in which helps to investigate the influence of chemical modifications and carbonization of the adsorptive capacities of sawdust foe zinc copper and nickel. This metals help to evaluate ranged between 0.130% and 0.393% while volatile matter range between 0.120% in nickel for unmodified and 0.40% in chemically modified. Results also show highest value of volatile matter (0.401%) in modified while lowest value of (0.120%) was recorded in unmodified by nickel as a catalyst. Highest value of ash content (21.05%) was observed or recorded in chemically modified samples while cowest or least in an modify samples Result of fixed carbon show general increase in carbonized than unmodified and modified. These result show that nickel, copper and zinc have good adsorption capacity for unmodified, chemically modified and carbonized form of sawdust.
