Based on the strong coordination between glutamate and electrochemically active silver ion(Ag+),the oxidation peak current of Ag+ decreases and the new oxidation peak is generated, we constructed a non-enzyme electrochemical sensor for detecting glutamate.The results show that, in the range of 0.5-2 μmol·L-1,the decrease of Ag+ oxidation peak current has a good linear relationship with glutamate concentration, and the detection limit is 0.1 μmol·L-1.In the range of 8-100 μmol·L-1,the increase of new oxidation peak current has a good linear relationship with glutamate concentration, and the detection limit is 8 μmol·L-1.The sensor can be applied to the detection of sodium glutamate in monosodium glutamate with high recovery rate, which provides a new idea for rapid, simple, and accurate electrochemical detection of glutamate.
