title: Decomposition Products of s-Triazine Herbicides by Electron-Transfer in Acidic Aqueous Media
abstract: The reduction of atrazine and terbutylazine was preceded by protonation equilibrium. Three protonation sites of the s-triazine molecule determined the structure of the final reduction product. Protonation was investigated by the change of UV-Vis spectra. Two slightly different pKs corresponding to protonation on N5 and N1 heteroatoms were evaluated. The principal reduction pathway involved the cleavage of a chlorine atom. A small quantity of desethylatrazine was detected in the most acidic media.
