Measurement of zgr; potential of YBa2Cu3O7minus;dgr;from the adsorption of hydronium ions (H+,thinsp;OHminus;)

摘要

The adsorption of hydronium ions, H+and OHminus;, on YBa2Cu3O7in electrolytic solution is measured. The curve of the zgr; potential (zeta potential) of YBa2Cu3O7gives the pointhyphen;ofhyphen;zero zgr; potential (pzzp). The electronegativity of YBa2Cu3O7can be found from the pzzp. The experimental value of the electronegativity is compared with the calculated result.
