摘要： 用石墨粉填充苯乙烯-丙烯腈共聚树脂(AS树脂),挤出成型,制取AS树脂/石墨复合导电材料电极。用红外光谱、循环伏安等手段表征了电极的结构及特性。电极对测定Ag+有较好的选择性、稳定性和再现性,并较一般玻碳电极更易化学修饰。

Abstract: 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.

Key words: polymer/graphite electrode, acrylonitrile-styrene copolymer, trace silver determination, modified electrode, electrochemical property
