The environmental engineering faculty are involved in a broad range of research that exhibits excellence in both fundamental and applied areas. A significant and unique strength of the group is its wide range of research expertise and, more importantly, the utilization of this expertise in concept development and application. Current research encompasses the sub disciplines of air, soil, surface water, and groundwater. Catalyzed Peroxide Treatment Treatment of hazardous and industrial wastes using catalyzed peroxide is an emerging area that is applicable to a variety of contaminants and contaminant matrices. This process technique has been shown to be effective for complete or partial destruction of recalcitrant materials in both soils and industrial waste streams.
Destruction is afforded by hydroxyl radical that is formed under appropriate reaction conditions.
This work is being extended to high pressure catalyzed peroxide oxidation where significant reductions in peroxide requirements are anticipated. In addition, the use of native minerals as natural catalysts is being investigated. The role of hydroxyl radical in the atmosphere is well established as a key molecule in almost all atmospheric chemical cycles. Work at WSU is aimed at the development of a method for measuring ambient levels of the very reactive OH molecule, and using this method to document diurnal and seasonal variations in OH levels as a basis for evaluating atmospheric chemical models. Studies are underway at WSU to measure deposition rates of hydrogen peroxide to vegetation and to model the uptake of H2O2 by plants.
