a b s t r a c tGlyphosate, one of the organophosphate herbicides, has been widely used in the word. The removal of glyphosate was comparatively investigated by MnO 2 oxidation, electrochemical oxidation, and electrochemically assisted MnO 2 oxidation (electro-MnO 2 ) processes. were indentified in the initial phase of the MnO 2 oxidation and electro-MnO 2 processes. Glycine was further decomposed to glycolic acid and NH 3 -N in the MnO 2 oxidation process; in contrast, glycine was oxidized into oxamic acid, glycolic acid and N-contained intermediates, and N-contained intermediates could be finally oxidized into acetic acid, NH 3 -N and NO Crown
