AI Technical Summary
Technical Problem
In the existing technology, the detection methods for triclosan rely on large, expensive instruments and cannot be analyzed quickly. Conventional electrochemical sensors have narrow linear ranges, high detection limits, and poor anti-interference performance.
Method used
A cobalt-iron bimetallic doped carbon-based composite material CoFe@C was used as the electrode material. An electrochemical sensor was prepared by high-temperature pyrolysis of ZIF-67 and detected by combining cyclic voltammetry and differential pulse voltammetry.
Benefits of technology
It achieves high sensitivity detection of triclosan, with low detection limit, wide linear range and strong anti-interference ability, and is suitable for detection of practical samples.
