NOVELTY - Thin-layer polymer sensitive film solid-contact ion selective electrode based on pulse galvanostatic control comprises a conductive substrate, and sensitive film. USE - Thin-layer polymer sensitive film solid-contact ion selective electrode based on pulse galvanostatic control used in electrochemical sensor, and to industrial analysis, marine environment monitoring, medical sanitation and soil analysis. ADVANTAGE - The thin-layer polymer sensitive film solid-contact ion selective electrode based on pulse galvanostatic control has wide application prospect in the detection of the ion, reduces the pre-activation time of the electrode, improves the detection performance of the electrode, and exhibits excellent reversibility. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for detecting thin-layer polymer sensitive film solid contact ion selective electrode based on pulse constant current control, involving: a. inserting the electrode into the to-be-detected sample, applying negative electrode pulse constant current to the thin-polymer sensitive film solid contact type ion selective electrode; b. controlling the ion flux of the to-be-detected ion in the to-be-tested solution through the thin-layer polymer sensitive film phase, to extract the ion flux to the sensitive film phase, generating a timing potential response, to detect the ion.
