聚合物/石墨复合材料电极及其在银离子测定中的应用
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.

Polymer/Graphite Composite Electrode and Its Application in Trace Silver Determination
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.
