A study of metal ions in aqueous solution using NMR Spectroscopy.
Full text access: Open
A study was carried out to investigate the properties of certain metal ions in solution using multinuclear magnetic resonance techniques as the mode of analysis.
The majority of this work has involved the collection of numerouschemical shift measurements especially for the lead-207 nucleus and the cadmium-113 nucleus. The data obtained from these experiments have been utilized in several ways. Experiments have shown that the nuclei in different environments behave differently towards concentration and temperature changes. The nuclei investigated also appear to have quite specific characteristic behaviour when attached to different atoms of ligands, for example, the resonance signal for lead-207 attached to oxygen will be different from the lead-207 signal attached to nitrogen. The chemical shift data were also used to calculate some equilibrium constant (K) values using a proposed theoretical model.
Some relaxation time measurements for various lead compounds have been collected in order to further characterise the nature of a particular lead species in solution. The theories involved with relaxation, the mechanisms of relaxation and the practical aspects connected with these experiments have been discussed.
