摘要

合成了N,N ' -双(2,4-二甲氧基苄基)乙二胺,并以其为膜载体制备了一种新型的对Fe3+离子具有选择性的聚氯乙烯膜电位传感器。在7.3·10−8 -1·10−1 M的浓度范围内,该传感器的超纳恩斯坦斜率为19.5 mV / 10年,检测限为7.3·10−8 M。传感器在30秒左右的时间内对Fe3+离子的检测显示出线性电位响应,并且具有不少于9周的寿命,且没有任何电位发散。所选择的传感器在pH为3.6 ~ 10的水溶液中,即使存在其他金属阳离子,也对Fe3 +离子具有较高的选择性。

Novel N,N’-bis(2,4-dimethoxybenzylidene)ethylenediamine PVC membrane electrode for the potentiometric iron selective sensor based on Schiff base ligand
N,N’-bis(2,4-dimethoxybenzylidene)ethylenediamine was synthesized and used as a membrane carrier to create a novel poly(vinyl chloride) membrane potentiometric sensor that is selective especially for Fe3+ ions. The super-Nernstian slope of the projected sensor was 19.5 mV per decade over a concentration range of 7.3·10−8 –1·10−1 M having detection limit at 7.3·10−8 M. The sensor displayed a linear potential response for the detection of Fe3+ ions in about 30 seconds, and it had a lifespan of no less than 9 weeks without lacking any potential divergence. The selected sensor showed high selectivity in water solutions in relation to Fe3 + ions, even in the presence of other metal cations in the pH range of 3.6–10.
