The semi-empirical spectrophotometric (SESp) method, for the indirect determination of ion exchange constants (KXBr) of ion exchange processes occurring between counterions (X- and Br-) at the cationic micellar surface, is described in this article. The method uses an anionic spectrophotometric probe mol., N-(2-methoxyphenyl)phthalamate ion (1-), which measures the effects of varying concentrations of inert inorganic or organic salt (NavX, v = 1, 2) on absorbance, (Aob) at 310 nm, of samples containing constant concentrations of 1-, NaOH and cationic micelles. The observed data fit satisfactorily to an empirical equation which gives the values of two empirical constants These empirical constants lead to the determination of KXBr (= KX/KBr with KX and KBr representing cationic micellar binding constants of counterions X and Br-). This method gives values of KXBr for both moderately hydrophobic and hydrophilic X-. The values of KXBr, obtained by using this method, are comparable with the corresponding values of KXBr, obtained by the use of semi-empirical kinetic (SEK) method, for different moderately hydrophobic X. The values of KXBr for X = Cl- and 2,6-Cl2C6H3CO2-, obtained by the use of SESp and SEK methods, are similar to those obtained by the use of other different conventional methods.Sodium 2,6-dichlorobenzoate(cas: 10007-84-8Application of 10007-84-8) was used in this study.
Sodium 2,6-dichlorobenzoate(cas: 10007-84-8) belongs to organochlorine compounds. The wide structural variety and divergent chemical properties of organochlorides lead to a broad range of names, applications, and properties.Application of 10007-84-8 Organochlorine compounds have wide use in many applications, though some are of profound environmental concern, with TCDD being one of the most notorious.
