Masters Thesis-Open Access
A separation scheme has been developed by utilizing Solid-Phase Extraction cartridges in order to isolate and characterize the charge of metals and their complexes in natural waters. These species can be analyzed by Atomic Absorption Spectroscopy (AAS), Inductively Coupled Plasma (ICP), and Ultraviolet-Visible Spectrophotometry (UVVIS).
This separation scheme would permit the determination of the concentration of metals, as well as providing information about the forms in which the metals exist, e.g., charge of metallic complexes.
Synthetic metal complexes were prepared in the laboratory in order to study the separation scheme as well as trying to understand the binding stability of the complex under controlled pH and concentration. Lake water samples were also analyzed by the separation scheme. Different forms of metal species were detected and found distributed in different ratios for different lakes.
