Abstract

The agricultural byproduct, corn cobs, was chemically activated by 20%nitric acid for 24hours and was used for removal of toxic ions of copper, zink and lead ions from waste solutions. The maximum removal of such ions in relation to certain factors; contact time, pH values, temperature, and sorbent mass were investigated. The data obtained cleared that, the maximum removal of lead, copper and zink ions by sorbent material were found to be 91%, 87%and 76%, respectively after two hours shaking time. Also, the increase in pH and temperature resulted in high removal of toxic ions. Accordingly, chemically activated corn cobs could be used eventually for treatment of liquid wastes containing toxic ions
