Two Advanced Oxidation Processes, namely vacuum-ultraviolet (VUV) photolysis at 172nm and ultraviolet/hydrogen peroxide (UV/H(2)O(2)) were investigated for the degradation of anatoxin-a in aqueous solutions. Solutions of anatoxin-a-fumarate were treated with VUV light at 172nm with a UV dose of 200 mJ/cm(2), where fumaric acid served as a reference compound for a competition kinetics analysis. The second-order rate constant for the reaction between anatoxin-a and the hydroxyl radical was found… CONTINUE READING
