Volta metric behavior of mesotrione using silver/amalgam electrode we examined in this paper. Mesotrione belongs to the triketone group of herbicides. It is used against weeds in corn and operates by inhibition of 4-hydroxyphenyl piruvate in plants. There is little information about mesotrione as its presence in the market is short. For its wider application in the future, it is important to know details of its chemical characteristics and redox processes, including biogeochemical transformation and migration after application in agricultural land, which could contribute to its more efficient and safe application. The technique of cyclic voltammeter with conventional three-electrode cell and electrochemical workstation was used for the investigation of electrochemical behavior of mesotrione. Cyclic voltamograms of mesotrione were recorded at pH values 6, 8, 10 and 12. Several peaks were obtained at certain values of the potential and they were attributed to the reduction of two carbony...l groups (in position 1 and 3 of cyclohexane ring), the third carbonyl group and nitro group. The maximum current value was at pH 12.
