SENIOR RESEARCH:
The objective of this research is to develop an analytical method to measure the forms of metals in equilibrium with natural organic substances. The solution were analyzed using a 200 MHz Bruker DRX solution phase Nuclear Magnetic Resonance (NMR) spectrometer. A water suppression technique was utilized in our lab and has shown good results in our previous studies. In implementing this technique, a solution of Copper (II) perchlorate hexahydrate was dissolved in deionized water and diluted with DMSO-d6. Copper concentration studied were 0.25, 0.50, 0.75, 1.00 mM. EDTA was also used as a model compound for natural organic matter.
