A new PVC membrane electrode for manganese(II) ion based on a recently synthesized Schiff base of 5-[(4-nitrophenylazo)-N-hexylamine]salicylaldimine is reported. The electrode exhibits a Nernstian response for Mn(2+) ions over a wide concentration range (4.0x10(-7) to 1.8x10(-2)molL(-1)) with a slope of 30.1 (+/-1.0). The limit of detection is 1.0x10(-7)molL(-1). The electrode has a fast response time ( approximately 10s), a satisfactory reproducibility and relatively long life time. The proposed sensor revealed good selectivities over a wide variety of other cations include hard and soft metals. This electrode could be used in a pH range of 4.5-7.5. It was used as an indicator electrode in potentiometric titration of manganese(II) ions with EDTA solution.
报道了一种基于最近合成的5-[(4-硝基苯偶氮)-N-己胺]水杨醛亚胺席夫碱的新型锰（II）离子PVC膜电极。该电极在较宽的浓度范围（4.0×10⁻⁷至1.8×10⁻²molL⁻¹）内对Mn(2+)离子呈现能斯特响应，斜率为30.1（±1.0）。检测限为1.0×10⁻⁷molL⁻¹。该电极响应时间快（约10秒），重现性良好，使用寿命相对较长。所提出的传感器对包括硬金属和软金属在内的多种其他阳离子具有良好的选择性。该电极可在pH值为4.5 - 7.5的范围内使用。它被用作指示电极，用于用EDTA溶液电位滴定锰（II）离子。
