LITHIUM BROMIDE CONCENTRATION MEASURING METHOD AND LITHIUM BROMIDE CONCENTRATION MEASURING SYSTEM OF LITHIUM BROMIDE AQUEOUS SOLUTION

摘要

PPROBLEM TO BE SOLVED: To provide a lithium bromide concentration measuring method of lithium bromide aqueous solution capable of grasping the lithium bromide concentration in real time even in a system other than that in the atmospheric pressure. PSOLUTION: This lithium bromide concentration measuring method comprises a measuring end setting process P1 for setting each detection end of a thermometer and a pH meter in the lithium bromide aqueous solution which is a measuring object, a temperature measuring process P2 for measuring subsequently the temperature of the lithium bromide aqueous solution by the thermometer, a pH measuring process P3 for measuring in parallel pH of the lithium bromide aqueous solution by the pH meter, and a concentration measuring process P4 for determining the lithium bromide concentration in the aqueous solution from the temperature acquired from the temperature measuring process P2 and the pH value acquired from the pH measuring process P3.
