BF4- post-processing method and BF4- measuring method of measurement

摘要

PROBLEM TO BE SOLVED: To suppress positive errors of measured values to be generated when BF₄^- concentration is continuously measured for over twice in a method for circulating test solution to a circulation path to measure the BF₄^- concentration of the test solution by a liquid film type BF₄^- electrode installed on the circulation path.;SOLUTION: A BF₄^- measurement method is constituted so as to circulate BF₄^- solution to a circulation path as post-processing of measurement of test solution when the test solution is circulated to the circulation path to measure BF₄^- concentration of the test solution by a liquid film type BF₄^- electrode installed on the circulation path.;COPYRIGHT: (C)2013,JPO&INPIT
