▎ 摘　　要

NOVELTY - Preparing electrochemical sensor for simultaneously detecting bisphenol A and bisphenol C, comprises (i) ultrasonicating single-walled carbon nanotubes in a concentrated sulfuric acid-concentrated nitric acid mixture, adding deionized water and centrifugally washing until washing liquid is neutral and solid freeze-drying, (ii) placing in ethylene glycol, adding platinum chlorate, adjusting pH value of mixed solution, and sonicating, placing solution in autoclave, reacting, (iii) adding titanium aluminum carbide to hydrofluoric acid solution, and reacting, filtering it with polytetrafluoroethylene to obtain titanium carbide, (iv) mixing single-walled carbon nanotube dispersion modified by platinum nanoparticles and graphene oxide/titanium carbide dispersion, and filtering with polytetrafluoroethylene, (v) adding to ethanol solution and sonicating (vi) drop-coating onto working electrode, and drying deposition, (7) placing in buffer, applying a constant voltage. USE - The method is useful for preparing electrochemical sensor for simultaneously detecting bisphenol A and bispheneol C used in industrial and commercial use of EDCs. ADVANTAGE - The electrochemical sensor has high sensitivity, reduced detection limit and wide detection range. The electrode modified material has convenient scale production, and has wide application prospect.
