Abstract


The complexation of molybdenum(VI) with methyliminodiacetic acid (MIDA) at pH = 6.00, T = 298 K , I = 0.1 mol.dm-3 of sodium chloride and different water + methanol solutions (0-45% v/v)  was studied by using potentiometric and UV spectrophotometric measurements. The stability constants values were calculated and their trends have been interpreted by using the Kamlet-Abboud-Taft (KAT) model in order to investigate the role of different specific and non-specific interactions in the aqueous solutions of methanol. Hyperquad 2013 and Microsoft Excel 2010 softwares have been used for the calculations.
