Abstract

(a) These methods cover the determination of sodium and potassium ions in industrial water and water-formed deposits, using both direct-measuring and internal-standard type flame photometers. A procedure for each type is included in these methods. The direct-intensity method is used for both types of instrument in the analysis of water of high purity. Three methods are given, as follows: (b) Non-instrumental methods for sodium and potassium ions in industrial water are given in the Methods of Test for Sodium and Potassium in Industrial Water (ASTM Designation: D 1127).
