Summary:In order to determine automatically potassium ion and sodium ion of samples such as sea water, brine, mother liquid, bittern and common grade salt by using Technicon's Auto-Analyzer, a flowdiagram of flame photometer was prepared and examined. The results were as follows: The sample solution was mixed with LiNO3 solution as rithiuminternal standard substance. And then, it was mixed into the flame photometer and the potassiumion and sodium ion were measured. In this method the calibration curve was linear to the concentration of potassium ion and sodiumion up to 100mg/liter respectively. The accuracy of this method was comparable to the ordinarymethod with the coefficient of variation under 0.6%. The speed of analysis was continuously 40-70 samples per hour excluding preparation and dilution of sample.
