Abstract
Disclosed are microwave assisted methods and systems for decontaminating a variety of contaminated surfaces. The systems and methods comprise treating the surfaces with benign chemical formulations followed by exposing to microwave irradiation for short periods of time to achieve at least 6-log reduction in biological contaminants including spores of B. anthracis, B. thuringiensis, and P. roqueforti. Chemical formulations may comprise copper (II) chloride in water. The formulations may include a surfactant such as a polyethylene sorbitol ester surfactant.
