Summary:Title screen
In this paper the L-glutamate electrochemical behavior on a carbon-containing electrode modified with gold in simulated solutions by cyclic voltammetry have been studied. The analytical signal of glutamate reduction at the potential of -0.8 V in pH 9.19 has been found. It has been determined that the cathodic reduction of glutamate is irreversible and mainly controlled by diffusion in the reduction electrode process of glutamate. The conditions for glutamate determination in simulated solutions by voltammetry have been found. The plots of current versus concentration present a linear behavior from 3.2·10{-4} to 2.5·10{-3} M. The detection limit is 4.4 10{-5} M. The glutamate determination in simulated solutions has resulted in acceptable deviation from the stated concentration where relative errors are -2.7 to +2.6%.
