硝酸根离子选择电极的研制,国内外已有不少报导,并有商品电极出售。其中大多数为液膜电极和 PVC 膜电极。1971年 R.W.Cottrall 和 H.Frieser 应用钙液膜电极材料与 PVC 制成涂丝钙离子选择电极。后来,有人以铂丝、PVC 和季胺盐制成硝酸根等各种离子涂丝电极,并在各方面获得广泛应用。我们在前人工作的基础上,用铂、铝、铜等金属丝作为基体,以7402·NO_3 季胺 Nitrate ion selective electrode development, there are many reports at home and abroad, and the sale of goods electrodes. Most of them are liquid film electrodes and PVC film electrodes. 1971 R.W.Cottrall and H. Frieser application of calcium liquid membrane electrode material and PVC made of coated calcium ion selective electrode. Later, it was made of platinum wire, PVC and quaternary ammonium nitrate nitrate ions and other coated wire electrode, and in all aspects of access to a wide range of applications. We work on the basis of the predecessors, with platinum, aluminum, copper and other metal wire as a matrix to 7402 · NO_3 quaternary ammonium
