Sekundarni naslov: | POTENTIOMETRIC DETERMINATION OF Cu 2+ USING ION SELECTIVE ELECTRODES |
Sekundarni povzetek: | The following diploma dissertation describes the use of the carbon paste electrode modified with copper salts. The electrodes were used for the potentiometric determination of copper concentrations by direct potentiometry and potentiometric titrations. When using direct potentiometry, we took measurements in the concentration range from 10-5 to 10-1 mol/L. We also analyzed the response times of the electrodes and determined which medium is the most appropriate to store the electrode in before and after its use. Out of all the electrodes tested, the one prepared with 200 mg of carbon paste and 120 mg Cu2S proved to be the most responsive. Cu2S was prepared using the sonochemical method. This electrode was selective and its measured potential increased proportionally to the concentration of copper solutions. The slope of the electrode was -22 ± 0.16 and was slightly lower than the theoretical one. |
