【摘要】 <正> 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。 三氧化铬双吡啶络合物参照文献方法制得。称取10mg电活性材料置于烧杯中,加数滴丙酮、0.6ml邻苯二甲酸二丁酯、5ml四氢呋喃、再加入200mg PVC粉,迅速搅更多还原

【Abstract】 A new type of PVC membrane ISE of pyridine as well as of N, N--dimethylaniline wasprepared by using chromium trioxide-pyridine complex as active material. The potentialNernst 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 itspotential Nernst response range was found to be the same as chromium trioxide-pyridinecomplex.更多还原
