摘要： 三氧化铬双吡啶络合物在有机合成中作为氧化剂而得到应用,作为化学传感器电活性材料的研究尚未见文献报导。我们以三氧化铬双吡啶络合物为电活性材料研制了吡啶、N,N-二甲基苯胺通用的PVC膜离子选择电极。

Abstract: A new type of PVC membrane ISE of pyridine as well as of N, N-dimethylaniline was prepared by using chromium trioxide-pyridine complex as active material. The potential Nernst responses for pyridinium and N, N-dimathylanilinium ions ranged in 1?10-1-1?10-5M and 1?10-1-6.3?10-6M respectively. Pyridinium chlorochromate C5H5NHCrO3Cl can also be used as active material and its potential Nernst response range was found to be the same as chromium trioxide-pyridine complex.
