摘要：
A simple and rapid method is introduced for the determination of dissociation constants of organic compounds by means of UV-visible spectrophotometry. It is applicable to the compounds whose concentrations or extinction coefficients are not determined. It provides more exact dissociation constants than other methods, even for polyprotic compounds with almost equal pK(a) values and compounds with extremely acidic or extremely basic properties.
