The graphite-AS(acrylonitrile styrene copolymer) composite electrodes were prepared and characterized by IR and cyclic voltammetry. The electrodes were applied in determination of trace amount of Ag⁺ in waste water and showed a higher stability, reproductivity and selectivity. Owing to the presence of the abundant polar groups from AS, the electrodes showed an advantages of being further modification with NH₂OH ° HCl, giving an additional property.
