Abstract
A method for the separation of hydrogen ion, characterized in that a substance having a conjugate base (A ) of an acid (HA) as a functional group is used as a stationary phase, and an electrolyte containing a cation having a larger ion exchanging force than that of hydrogen ion is used as an eluent. The method allows the selective separation of hydrogen ion and the quantitative analysis thereof with high precision.
