概要:
金沢大学理工研究域<br />Relationships between ion-chromatographic retention behaviors of several anions and their dissociation constants were studied from two standpoints. In Part 1,the influence of the dissociation equilibria on the measured capacity factor of a sample was interpreted. In this study, the ratio of the capacity factor of the sample to that of a standard anion was used for the analysis of the retention behavior. The dissociation constants and the ratio of the capacity factors of various species of the sample to that of the standard were calculated and the retention behavior was estimated. In Part 2,the differences in the retention times of substituted benzoate anions having similar structure were analyzed by dividing the substituent effect into an LFER-applicable effect term, a steric effect term and a positional effect correction term. The first was introduced by putting the theory of linear free energy relationships into the relationship between the anion-exchange equilibria and the dissociation equilibria. The second depends on kind and number of the introduced substituents, and the last on the position of them. Furthermore, the estimation of the retention times of these anions and the determination of the dissociation constants of substituted naphthoic acids were done. 続きを見る
