Abstract
The present invention relates to chloride-selective electrodes which comprise insoluble metal salt layer and a protecting membrane formed of hydrophilic polyurethane thereon, wherein the hydrophilic polyurethane coated chloride-selective electrodes show fast activation and response time and are usefully employed to accurately measure the chloride by reducing the interference from bromide and iodide or preventing the surface of the electrode from protein adsorption.
