AI Technical Summary
Existing methods are difficult to efficiently and conveniently detect and quantify the concentrations of monochloramine and ammonia in liquid samples, especially under different environments, and are easily affected by free chlorine, dichloramine or trichloramine.
A device and method based on electrochemical sensors were adopted, utilizing the Berthelot chemical reaction, and a coupling agent containing phenol derivatives and transition metal-based complexes was coated on the working electrode. This was combined with electrochemical voltammetry, especially differential pulse voltammetry, to achieve highly sensitive determination of monochloramine and ammonia.
A high-precision, portable electrochemical analysis system is provided, which can accurately determine the concentration of monochloramine and ammonia over a wide range, avoiding interference from other chloramines, and is suitable for rapid detection in various environments.
