季铵—水杨酸根电极的研制与应用已有报导,本文研制了PVC膜乙基紫—水杨根酸离子选择性电极。实验证明:以乙基紫阳离子作为离子交换定域体,可与季铵离子相媲美。而三苯甲烷染料分子中的取代基的π值可作为评价离子交换定域体性能优劣的一种参数。
Development and application of quaternary ammonium-salicylate electrode It has been reported that PVC membrane ethyl violet-salicylic acid ion selective electrode was developed in this paper. Experiments show that: ethyl violet cation as ion exchange domain, quaternary ammonium ions comparable. The π value of the substituent in the triphenylmethane dye molecule can be used as a parameter to evaluate the performance of the ion exchange domain.
