Volta metric Behavior of Mesotrione using Silver/Amalgam Electrode

Abstract

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