▎ 摘　　要

NOVELTY - Anti-interference material comprises carboxylated material; the carboxylated material includes at least one of carboxylated material containing conjugated π bonds and carboxylated molecular sieves. USE - The anti-interference material is useful for anti-interference film used in electrochemical sensor and color test paper (claimed). ADVANTAGE - The anti-interference film: is simple to prepare; can avoids process of interfering substances, saves detection time, and improves detection accuracy, and its anti-interference effect is more than 30 times that of the existing process film. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: Anti-interference film, comprising the anti-interference material. Preparing anti-interference film, comprising performing film-forming treatment including anti-interference material to obtain anti-interference film. Electrochemical sensor, comprising anti-interference film.
