    Abstract

    (a) These methods cover the determination of sodium and potassium ions in industrial water and waterformed 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: Sections Method A. Analysis of Industrial Water 8 to 13 Method 1 Analysis of High-Purity 1 dustrial Water 14 to 19 Method C. Analysis of Water-Formed eposits 20 to 25 (b) N n-instrumental methods for sodium an potassium ions in industrial water are given in the Methods of Test for Sodium and Potassium in Industrial Water (ASTM Designation: D 1127).
