摘要：
Chemical micro-sensor for the detection of Cu2+ ions in solution was prepared. Cu-Ag-S sensing material is build by electrolysis of copper - silver RF sputtered thin film. Analytical behaviour of developed sensor was fully characterised in terms of sensitivity, selectivity and stability. The potentiometric measurements showed a quasi-Nernstian behaviour with a detection limit close to 10(-6) M. In the presence of interfering ions the sensing system is very selective, since low selectivity coefficients are obtained versus various ionic species. The very first measurements carried out in waste waters are presented.
