Sensitive detection of luteolin in peanut shell based on titanium carbide/carbon nanotube composite modified screen-printed electrode

The preparation of d-Ti3C2Tx/MWCNTs/SPE and schematic diagram of electrochemical detection of luteolin was shown in Fig. 1. The SPE was coated with 7 μL d-Ti3C2Tx/MWCNTs dispersions accurately drew by pipettor, and then dried under infrared lamp to form the modified electrode. The modified electrode mainly uses cyclic voltammetry (CV) and differential pulse voltammetry (DPV) to detect luteolin. Each electrochemical measurement was repeated at least three times with different electrodes under the same conditions.
