Ozonation of humic and fulvic acids in aqueous solutions and in the presence of H 2 O 2 was studied at ozone doses of 33, 38 and 47 mg/l. Chemical oxygen demand (COD) and total organic compounds (TOC) of these compounds were tested. It was found that COD and TOC can be removed effectively by ozonation in the presence of H 2 O 2 . At 0.78 mg O 3 /mg COT and 0...
Irgarol 1051 (2-methylthio-4-tert-butylamino-6-cyclopropylamino-s-triazine) is a herbicide analogue that is added to antifouling agents used on ships. Our former study on its degradation in sunlight suggested that unknown photosensitizers in natural waters accelerated the photodegradation to the degradation product, M1. In this study, the photodegradation of Irgarol in water was investigated in the...
