Table 6.8 shows that the fastest depletion of atrazine occurs under Fenton s reagent. Arnold et al. (1995) demonstrated that OH may react with Ch at low pH to produce HOC1 and Cl2, causing underestimation of Cl concentrations, but the results suggest that Cl- scavenging by OH was minimal. Dechlorination and dealkylation occur simultaneously, and the batch treatment showed that dechlorination occurred more readily with alkylated s-triazines. Chlorinated products accounted for a large part of s-triazines present upon completion of Fenton s reagent.
