Abstract : The electrochemical reduction of Vitamin B13 (orotic acid) at the dropping mercury electrode (DME) has been investigated. The polarographic behavior of orotic acid in Britton-Robinson (BR) buffer solutions (pH 2-12), in unbuffered solution, in acidic, and also in alkaline solution was measured. The study showed that, the effect of Hg-height on the limiting current and the effect of pH on each of the limiting current and the half-wave potential of the waves are diffusion controlled. The data also showed that under the optimum experimental conditions, a linear calibration graph was obtained on plotting the concentration of orotic acid versus the height of the reduction wave. A detailed mechanism for the reduction of orotic acid at the dropping mercury electrode correlating the nature of the orotic acid species and its reduction in different media, is proposed.
