  • Complexation of Aluminum Ions with Formic Acid Under Acidic Condition: 27Al NMR, ESI-MS, and DFT study#U#UR

    Etou, M; Yoshida, M; Okaue, Y; Inoue, T; Yokoyama, T

    To understand the behavior of aluminum ions (Al3+) in strongly acidified soil environments, complexation between Al3+ and formic acid (FA), a natural monocarboxylic acid, at pH 3 was investigated using NMR, ESI-MS, and DFT techniques. In the presence of FA, two new 27Al NMR peaks appeared at high magnetic fields, in addition to a peak due to Al(H2O)63+, suggesting the formation of monodentate 1 : 1 (AlFA2+) and 1 : 2 (AlFA2+) complexes. The trends observed in the 27Al NMR analysis of the Al-FA complex was well represented by DFT calculations (i. e., move of the chemical shifts to the high magnetic field side, additivity low of the 27Al NMR chemical shift, and change in electron density of each Al3+ nucleus). The average conditional formation constants of the Al-FA complexes were determined to be log K1=1.17 and log K2=0.91 for the 1 : 1 and 1 : 2 complexes. The formation constant of the acetate complex was also determined to be log K=1.80 (1 : 1 complex). These results strongly suggest that natural monocarboxylic acids produced from the decomposition of organic compounds and certain bacterial activities show potential for the detoxification of Al3+, that is, complex formation with toxic Al species in acidified soil.

    Publisher：Journal of Solution Chemistry  

    The complexation between Al3+ ([Al(H2O)6]3+) and glycolic acid (GA, C2H4O3) which has a carboxyl group and a hydroxyl group in a molecule was investigated under acidic condition using 27Al NMR, 13C NMR and ESI–MS techniques. The five peaks including a peak due to Al3+ were observed in 27Al NMR spectra for the mixed solution of Al3+ and GA, suggesting the existence of at least four Al-GA complexes. The results of NMR and ESI–MS measurements revealed that GA and Al3+ can form one monodentate complex (AlGA2+) and three bidentate complexes (AlGA+, AlGA2−, and AlGA33−) complexes. From the deconvolution of 27Al NMR spectra and pKa value of GA, the conditional formation constants (log10 K) of each complex (GA/Al molar ratio of 25 in mixed solution) can be determined to be 0.94 (AlGA2+), − 0.96 (AlGA+), − 0.77 (AlGA2−) and − 2.21 (AlGA33−), respectively. In addition, the overall formation constant of three bidentate complex at pH 3 was also calculated to be − 1.65.
