A method for separating a hydroxide ion, characterized in that a hydroxide ion (OH-) in an aqueous solution is separated by a chromatograph. The method allows the separation and the measurement with high precision of a hydroxide ion which has not been achieved by a conventional pH titration method and pH meter method, and further allows the selective extraction and concentration thereof.
La présente invention concerne un procédé de séparation d'un ion hydroxyde, caractérisée en ce qu'un ion hydroxyde (OH?-¿) dans une solution aqueuse est séparé par un chromatographe. Le procédé permet, non seulement la séparation et la mesure à haute précision d'un ion hydroxyde qui n'a pas été obtenue par un procédé de titrage du pH conventionnel et un procédé de mesure du pH, mais également l'extraction sélective et la concentration de ces derniers.
