METHOD FOR SEPARATING HYDROXIDE ION AND METHOD FOR ANALYZING HYDROXIDE ION AND ION CHROMATOGRAPH |
摘要 |
<p>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.</p> |
