摘要

The removal of potentially toxic metal cations and anions from water is essential to providing safe water for consumption and recreation. The objective of this study was to evaluate the ability of activated carbons made from municipal sludge and poultry manure to remove certain meta! cations and anions from solution. Adsorption of the cations cadmium, copper, chromium, lead, nickel and zinc and the anions arsenic and selenium was carried out at pH 5. Lead was the most easily adsorbed cation by all three carbons, and the carbon from poultry cake adsorbed more cations, in general, than the other two carbons. However, arsenic and selenium were adsorbed more readily by the sludge-based carbon than the manure-based carbons. Combinations of both sludge- and poultry manure-based carbons may be efficacious toward the removal of low levels of cations and anions commonly found in municipal and industrial wastewater.
