“…Kula et al [10][11][12][13] reported the stability constants of molybdenum(VI) and tungsten(VI) complexes with EDTA, nitrilotriacetic acid (NTA), methyliminodiacetic acid (MIDA) and IDA by potentiometry and NMR techniques at different pH values and 25 ℃ and also determined their structures in solution. Zare et al 14 studied molybdenum(VI) and tungsten(VI) complexes with EDTA, IDA, EDDA and NTA at 25 ℃ and an ionic strength of 3 mol•L -1 NaClO 4 using a potentiometric technique.…”

Complexation of two ligands, iminodiacetic acid and ethylenediamine-N,N'-diacetic acid, with molybdenum(VI) was studied in aqueous solutions. Molybdenum(VI) forms a mononuclear complex with the aforementioned ligands of the type MoO 3 L 2-. All measurements have been carried out at 25 ℃ and different ionic strengths ranging from 0.1 to 1.0 mol•L -1 of NaClO 4 , with the pH justified to 6.0. Equilibrium concentration products and stoichiometry of the complexes have been determined from a combination of potentiometric and UV spectroscopic measurements.Comparison of the ionic strength effect on these complex formation reactions has been made using a Debye-Hückel type equation and Bronsted-Guggenheim-Scatchard specific ion interaction theory (SIT). Debye-Hückel theory predicted the first order effects on simple electrolyte solutions. Interactions between the reacting species and the ionic medium were taken into account in the SIT model. All of the calculations have been done by the computer program Excel 2000.

“…The original and further first works about the complexation of molybdenum(VI) with different aminopolycarboxylic acids were reported by Kula and coworkers. [18][19][20][21] A literature survey showed that although there are only a few reports about the complexation of molybdenum(VI) with ethylenediamine-N,N′--diacetic acid (EDDA) in methanol-water 22,23 and complexation of tungsten(VI) 24 and molybdenum(VI) 25 with EDDA in propanol-water mixtures, no paper was found on stability constants data in different water + methanol solutions for the interaction of molybdenum(VI) with MIDA. It was seen from literature data [22][23][24][25] that the stability constants increased with decreasing polarity of alcohol-water mixtures, which confirms the pattern that was obtained in the current research.…”

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 vol. %) was studied using potentiometric and UV spectrophotometric measurements. The values of the stability constants were calculated and their trends interpreted using the Kamlet-Abboud-Taft (KAT) model in order to investigate the role of different specific and non-specific interactions in aqueous solutions of methanol.
