Abstract: | ![]() The results of this research give ionic strength dependence patterns for the complexation of tungsten(VI) with methyliminodiacetic acid at T?=?298?K. The formation data reported in this work were obtained at different ionic strengths (0.1?I/mol·dm?3?1.0) of sodium perchlorate on the basis of Job??s continuous variation method, which show that a 1:1 complex forms at pH?=?7.50. UV experimental data were collected for the calculation of the stability constants according to the extended Debye?CHückel theory, the specific ion interaction theory and the parabolic model. Finally, these three models have been compared. |
