摘要
Humic acid extracted from peat was irradiated using Co-60 gamma irradiation. From the changes in UV absorption and a decrease in COD it appears that the humic substances were mineralized. These results suggest that radiation may hold promise as a treatment process for highly colored waters. (C) 2002 Published by Elsevier Science Ltd.
