The lower the solution pH the faster the degradation, with surface area normalized pseudo first order rate constants ranging from 2 (+/-1)x10^-^3 min^-^1 m^-^2 l for TBA at pH 2.0 to 4 (+/-2)x10^-^5 min^-^1 m^-^2 l for CDMT at pH 4.0. Hydrogenolysis (dechlorinated) products were observed for TBA and CDMT. Electrochemical reduction on mercury showed similar behavior for all of the triazines studied; the initial product of CDMT bulk electrolysis was the dechlorinated compound. The iron results are consistent with a mechanism involving the addition of surface hydrogen to the surface associated triazine. |
