Abstract
Extracted aquatic fulvic acid samples (HO10FA) from a brown lake Hohloh in the Black Forest (Germany) were ozonated at two different ozone doses and t hen chlorinated. In connection with liquid chromatography and further detec tion systems (UV and DOG) on gel matrix, a combined system (gel chromatogra py) was used for a detailed characterization of ozonated and post-chlorinat ed fulvic acid samples. The gel chromatographic characterization showed a s light decrease in DOC (14%) and SAC(254) (36%) at the end of 20 min ozonati on whereas the low ozonation time (5 min) caused increases in DOC (6%) and SAC(254), (56%).
