Abstract
In this research the interaction of dioxovanadiumV with iminodiacetic acid has been considered at 25 °C and pH=100–250 in an ionic strength range of 01 to 10 mol⋅dm−3 of NaClO4 by UV spectrophotometric and potentiometric techniques Only one species VO2H2L+ was assumed on the basis of two stoichiometric models The extended DebyeHückel theory predicts the first order effects in simple electrolyte solutions Interactions between the reacting species and the ionic medium are taken into account in the specific ion interaction model Parabolic specific ion interaction and extended DebyeHückel models have been compared and it has been shown that the parabolic model with two coefficients is satisfactory for this complexation reaction The results have also been compared with the literature values
