title: Oxidative removal of interferences in flow-injection potentiometric determination of chloride.
abstract: Direct potentiometric determination of chloride in a flow-injection system can be performed in the presence of excess bromide, iodide, sulphide and cyanide, when potassium bromate in nitric acid is used as the carrier solution. The hydrodynamics and temperature of such a system have been examined and various oxidants and indicating electrodes investigated. The analysis can be performed at a maximum rate of 120 samples per hour.
