Heavy metal and toxic element contamination of the environment has been increasing with increasing industrialization. Arsenic has become an element of particular concern because of its toxicity, which is oxidation state dependent. As(III) is observed to be much more toxic than As(V), as well the removal is more difficult than As(V) in traditional water treatment technology. In the present study, As (III) and As(V) removal was investigated using a zinc oxide nanomaterial that was synthesized using a titration/precipitation technique, and characterized using powder x-ray diffraction. In the present study, the kinetics of adsorption, the adsorption isotherms as well as the influence of contact time, concentration, pH, and temperature on the adsorption of As (III) and As (V) by zinc oxide was studied. The effect of some anions and cations on the adsorption of arsenic was also presented. All reactions concentrations were determined using Inductively Coupled Plasma Optical Emission Spectroscopy.
