The King group develops and builds analytical instruments for ultra-trace analysis of Fe(II), Fe(III), Mn(II), Cr(III), HOOH, superoxide, and phosphate in natural waters.
The King research group has several ongoing research projects. We are continuing to work with the Wells and Tripp groups at the University of Maine to develop novel sensors for iron in the ocean based on the specific interaction of DFB with Fe(III). Our second area of research is a kinetic study of the decay rate of superoxide in well-defined media. We are particularly interested in the decay rate of superoxide at nM concentrations where a number of first order decay pathways may effectively compete with the, well-characterized, second order decay pathway. Our third project is biogeochemical investigation of the Belgrade Lakes watershed. We are investigating the nutrient dynamics of each of the Belgrade Lakes and the redox dynamics of species like iron, HOOH, and superoxide at the lake surfaces (top and bottom).
His research group studies the role sunlight plays in regulating the surface water chemistry of lakes and the ocean. Many of these studies require novel analytical tools. King’s group is also actively involved in development of instruments for ultra trace analysis of Fe, Cu, Cr, Mn, H2O2, and O2– in the environment.
