摘要 以1,3-二(4-邻羟基苯亚胺次甲基)苯氧基丙烷为中性载体制备了PVC膜Fe3+离子选择性电极。该电极对Fe3+呈现出良好的选择性和近Nernst电位响应性能。电极斜率为21mV/dec,线性范围为3.0×10-5~1.0×10-1mol/L,检出限为1.0×10-5mol/L。采用交流阻抗技术研究了电极的响应机理,并将电极作为指示电极初步用于EDTA的电位滴定。 A PVC membrane electrode for iron ( Ⅲ )ions based on 1,3-Bis (4-carbonyl- phenylimino-methine) isopropoxybenzene as a neutral carrier was investigated. The prepared electrode displays a good selectivity toward iron (m) and exhibits a near Nemstian response for iron (re)over a linear range of 3.0×10^-5-1.0×10^-1mol/L with a detection limit of 1.0×10^-5 mol/L and a slope of 21 mV/dec. The electrode was used as an indicator electrode in potentiometric titration of iron(Ⅲ) with EDTA with satisfactory results.
