The average number of lactate ligands per zirconium ion is approximately 2 and is demonstrated to be relatively constant from p H 4-9.The lability of the lactate complexes increases as the p H is decreased.
Thanks are due as well to Henrik Krarup, who handled the samples that were sent to PSU. The nuclear magnetic resonance experiments were performed on the spectrometers at the Advanced Magnetic Resonance Imaging and Spectroscopy facility at the University of Florida Brain Institute.
Zirconium lactate solutions were characterized using Fourier transform infrared (FT-IR) spectroscopy, 'H, 13 C, and 17 nuclear magnetic resonance (NMR) spectroscopy, and potentiometry.
The results indicate that lactic acid is coordinated bidentate to zirconium via the alcohol and carboxylate groups.
Many family members and friends have encouraged me throughout the trying times over the last several years.
I am grateful for my fellow graduate students in the Materials Science and Engineering Department and the Adair research group who have made my time at UF more memorable and enjoyable.
