| description | The invention provides a sensor for simultaneously detecting tanshinone I and cryptotanshinone and a direct electrochemical method, an AuPd NWs/CFME electrode formed by modifying a carbon fiber electrode with AuPd NWs through electro-deposition is used as a working electrode, an Ag/AgCl electrode is used as a reference electrode, and a sample is detected through differential pulse voltammetry. A trisodium citrate reduction method is adopted to synthesize gold-palladium composite nanowires and form interlaced network structure AuPdNWs, an electrochemical sensor AuPdNWs/CFME is constructed on the basis of AuPdNWs, the electrochemical sensor AuPdNWs/CFME is utilized to carry out direct electrochemical detection on tanshinone I and cryptotanshinone in a sample, the synergistic effect of Au and Pd amplifies the catalytic action, and the electrochemical sensor AuPdNWs/CFME can be used for detecting the tanshinone I and cryptotanshinone in the sample. Compared with the prior art, the method provided by the invention |
