本文提出了一种制作光纤反射式体光电膜传感器的新方法。光电极膜由增塑的聚（氯乙烯）膜组成，其中离子载体溶解在纤维素支持物中。将带有染料指示剂1-（2-吡啶偶氮）-2-萘酚（PAN）的新光催化剂加入到新的流通池中，并优化进样系统，以在567 nm处测定5 × 10−5-10− 3 M范围内的Cu（II）。响应是可再现的，并且可以使用10− 2 M EDTA然后用水再生光催化剂。方法用于真实的样品中铜的测定。
A new procedure for constructing an optical fibre reflectance, bulk optode membrane type, sensor is presented. The optode membrane consists of a plasticized poly (vinyl chloride) membrane in which the ionophore is dissolved, entrapped in a cellulose support. The new optode with the dye indicator 1-(2-pyridylazo)-2-naphthol (PAN) was incorporated in a new flow-through cell and the injection system was optimized to determine Cu (II) at 567 nm in the range 5 × 10−5–10−3M. The response was reproducible and the optode can be regenerated using 10−2M EDTA followed by water. The method was applied to the determination of copper in real samples.
