Effect of Ozonation on the biodegradability of atrazine in GAC columns. Academic Article

abstract

• The biodegradation of atrazine as influenced by preozonation was studied in biological GAC columns. Metabolism of isopropyl-14C atrazine produced more 14CO2 than ring-UL-14C atrazine, indicating dealkylation was more rapid than ring cleavage. Preozonation increased mineralization of ring-UL-14C atrazine and, consequently, enhanced the performance of GAC columns. Sixty-two percent of the influent atrazine was converted to 14CO2 in columns that received ozonated atrazine and ozonated surface water, while 50% of the influent atrazine was converted to 14CO2 in columns that received untreated atrazine and ozonated surface water, and only 38% of the influent atrazine was converted to 14CO2 in columns with untreated influent.
