Abstract
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 byinhibition of 4-hydroxyphenyl piruvate in plants. There is little information about mesotrione as its presencein the market is short. For its wider application in the future, it is important to know details of its chemicalcharacteristics and redox processes, including biogeochemical transformation and migration after applicationto agricultural land, which could contribute to its more efficient and safe application. The technique of cyclicvoltammeter with conventional three-electrode cell and electrochemical workstation was used for theinvestigation of electrochemical behavior of mesotrione. Cyclic voltamograms of mesotrione were recorded atpH values 6, 8, 10 and 12. Several peaks were obtained at certain values of the potential and they wereattributed to the reduction of two carbonyl groups (in position 1 and 3 of cyclohexane ring), the third carbonyl group and nitro group. The maximum current value was at pH 12.
