The purpose of this work was to study the complex formation between Cu2+ and 3,7-dihydroxyl-l,5-diphenyloctahydro-1,5-diazocine(L). Difficulties have been encountered in getting a pure complex due toside reactions. Various methods have been used to analyze the complexation as well as side products. As complex formation can be detected by measuring eu2+ concentration with a specific ion electrode, wax bound CuS and CuO electrodes have been constructed and their behavior in ethanol solution evaluated so as to employ them in the analysis of the Cu 2+ and L system. Unfortunately, all electrodes change in time to a certain degree because they are affected by the components of the measured solutions, and "poisoned" by interfering ions or strong oxidants, etc. therefore, the possibility of renewing electrode sensor surface became an obvious advantage. Some electrodes cannot be renewed such as those based on silicone rubber or polyethylene membrane. A wax bound electrode is simple in structure and can be renewed by simply rubbing with a piece of filter paper. If not used in solution with very high temperature, the electrode can be used repeatedly for a very long period of time. The reproducible renewal of the electroactive surface, which will lead to the same calibration curve, becomes one of the advantages of this kind of electrodes.
