Patent Title: Malachite green selective electrode and manufacturing method thereof
Publication date: 2011
Publication number: CN102135522

Abstract: The invention provides a malachite green selective electrode and a manufacturing method thereof. The electrode is formed by combining a sensitive membrane, internal filling liquid, an internal ratiometric electrode, an electrode pole and an epoxy resin, wherein the sensitive membrane contains an electric active substance and a restricted-access media-molecularly imprinted polymer two-dimension functional material (RAM-MIPs). The RAM-MIPs two-dimension functional material introduced in the invention has the advantages of reducing diffusion coefficient of ions in the membrane and improving electrode selectivity and the like; simultaneously the internal filling liquid is optimized; the transmembrane ion flux can be inhibited effectively; and the detecting limit of the electrode is reduced to the magnitude of 10 to 9mol/L. By taking the malachite green selective electrode as an indicator electrode and by adopting a potential analysis method, the malachite green can be detected with high sensitivity and high selectivity; and the detecting speed is quicker, the required equipment is simple, the analysis cost is low, and the field detection on malachite green can be realized.
