A PVC membrane electrode for aluminium ion based on bis(5-phenyl azo salicylaldehyde) 2,3-naphthalene diimine (5PHAZOSALNPHN) as an ion carrier was developed. The electrode exhibits a Nernstian slope of 19.3+/-0.8 mV per decade and a linear range of 5.0x10(-6)-1.0x10(-2) M for Al(NO(3))(3). The limit of detection is 2.5x10(-6) M. It has a fast response time of about 10 s and can be used for at least 10 weeks without observing any deviation. The proposed membrane sensor revealed good selectivity for Al(3+) over a wide variety of other metal ions and could be used in pH range of 2.9-5.0. It was used as an indicator electrode in potentiometric titration of aluminium ion.
基于双(5-苯基偶氮水杨醛)2,3-萘二亚胺(5PHAZOSALNPHN)作为离子载体，研制了一种用于铝离子的 PVC 膜电极。该电极对 Al(NO(3))(3)表现出 19.3+/-0.8 mV 每 decade 的 Nernst 斜率和 5.0x10(-6)-1.0x10(-2) M 的线性范围。检测限为 2.5x10(-6) M。它具有约 10 s 的快速响应时间，并且可以在没有观察到任何偏差的情况下至少使用 10 周。所提出的膜传感器对 Al(3+)具有良好的选择性，对多种其他金属离子具有广泛的选择性，并且可以在 pH 值为 2.9-5.0 的范围内使用。它被用作电位滴定法测定铝离子的指示电极。
