Abstract |
Three types of potassium ion-selective electrodes were evaluated for suitability in monitoring or in-situ measurement applications. Each sensor was tested for the following parameters: accuracy, precision, temperature dependence, short and long-term stability, durability, sensitivity to variations in light intensity and flow conditions, response time as a function of temperature and potassium concentration, and variations between different manufacturers. The three potassium sensors (glass-membrane single electrode, glass-membrane combination electrode and liquid ion-exchange electrode) were evaluated at 10C and 25C in freshwater, synthetic seawater and natural seawater (35-, 20- and 5-ppt salinity). A description of the devices, the theory of their operation, and a summary of the test results are included. |
