Abstract

The electrochemical behavior of metal coated hollow fiber membrane electrodes is studied and their application to the amperometric detection of sugars in high-performance liquid chromatography (HPLC) is described. In the cyclic voltammetry in 0.15M NaOH of the nickel coated hollow fiber membrane electrode, broad reduction wave from Ni (III) to Ni (II) was observed, and the peak current decreased with the dependence on the concentration of glucose. This is because the elctrocatalytic oxidation of glucose by the metal oxide has been generated. The electrochemical detector for HPLC was produced in the nickel coated hollow fiber membrane electrode, and it was controlled in the potential of which the oxidation current of glucose was observed. It was found that the 8 mm electrode length was optimum for the detection of glucose in the flow system. In addition, electroconductive hollow fiber membrane electrode which covered with copper, gold, platinum was developed. The peak current of glucose and value of the noise in each electrode were measured. The detection limits (S/N=3) for glucoses were 9.8 pmol in case of Ni coated, 2.1 pmol on Cu, 3.5 pmol on Pt and 19.9 pmol on Au, respectively.
