Madison from the air

The Aquatic Chemistry group at UW Madison focuses on the formation and fate of reactive oxygen species (ROS) in water. These reactive species can be produced by photochemical reactions and by metal redox reactions and can lead to the transformation of aquatic pollutants. By studying these fundamental reaction mechanisms, our group aims to develop models and real world applications that can be used to improve water quality.
