Propazine (2-chloro-4,6-diisopropylamino-1,3,5-triazine) is a triazine herbicide used to control broadleaf weeds and annual grasses during the production of milo grain sorghum. This compound provides post-emergent protection by interfering with photosynthetic electron transport of target weeds. Tolerant crops are able to degrade the applied herbicide to nontoxic metabolites. Propazine is electrochemically active under acidic conditions. We report experimental evidence for the electrochemical dechlorination of propazine and reduction of the triazine ring using controlled potential electrolysis (CPE) in conjunction with IR, HPLC, NMR, and GC/MS. The information is useful for the development of electrochemical remediation and detection methods. This poster outlines our results.
