| Popis: | The specific aim of this work was the development of an electroanalytical method, based on a mercury-free sensor, for the determination of silver(I) and copper(II) used to treat pathogens in water distribution systems. Analysis of the two metals was performed in 0.1 M ammonia solution pH 9.0 using Square Wave Anodic Stripping Voltammetry (SWASV). The proposed method is based on the determination of copper, the addition of a masking agent (EDTA) to the solution and afterwards the determination of silver. A detection limit of 23 µg/L and 6 µg/L for 60 s of deposition time was obtained for copper and silver, respectively. Analysis of water samples was also reported. |
