Abstract
Abstract Tricaine (MS222) is a widely-used compound in fish anesthesia in aquaculture, transportation, and research laboratories, but its use has certain safety risks due to the lack of relevant laws and regulations. Herein, a simple and efficient one-step corrosion method was used to prepare a nanoporous gold (NPG) electrochemical sensor for detecting MS222. Under 0.1 M H2SO4 buffer solution, NPG showed a strong electrocatalytic redox effect on MS222, a wide linear range of 5 μg·mL−1 ~ 100 μg·mL−1, a low detection limit of as low as 0.29 μg·mL−1, and good applicability in actual sample of the recovery rate as 94.89%~107.93%. Thus, this work demonstrates the basic advantages of NPG and provides good application potential for the rapid detection of fishery anesthetic MS222.
