摘要

该研究提出了一种基于由 PbS 微颗粒、石墨(G)、多壁碳纳米管和石蜡油组成的复合传感层的全固态碳浆铜(II)选择性电位传感器的简单制造路线。对传感复合层的优化研究表明,含有 10 毫克 PbS、10 毫克 MWCNT、60 毫克 G 和 20 毫克 PO 的复合层具有最理想的电位性能。在 1.0 × 10-6-1.0 × 10-2 M 的浓度范围内,该传感器对铜(II)离子具有稳定的选择性线性响应(R2 = 0.9992),平均电位变化为 30.2 mV/decade。传感器的探测极限、响应时间和寿命分别为 5.0 × 10-7 M、15 s 和 3 周。制备的传感器已成功用于实际应用,可作为指示电极确定铜(II)滴定的终点,并测量添加了铜(II)的自来水样品中的铜(II)含量。

Fabrication of a novel potentiometric sensor based on graphite/carbon nanotube composite paste modified by lead(II)sulfide for efficient determination of copper(II) ions

A simple fabrication route for an all-solid-state carbon paste Cu(II)-selective potentiometric sensor on the basis of composite sensing layer consisting of PbS microparticles, graphite (G), multi-walled carbon nanotube, and paraffin oil has been propounded. Optimization studies for sensing composite layer signified that the composite contained 10 mg PbS, 10 mg MWCNT, 60 mg G, and 20 mg PO exposed the most promising potentiometric performance properties. The sensor displayed a stable and selective linear response to Cu(II) ions in the concentration range of 1.0 × 10−6–1.0 × 10−2 M (R2 = 0.9992) with an average potential change of 30.2 mV/decade. Detection limit, response time, and life-span of the sensor were determined as 5.0 × 10−7 M, 15 s, and 3 weeks, respectively. The fabricated sensor was successfully used in practical applications, serving as an indicator electrode to determine the end-point of Cu(II) titrations and to measure Cu(II) content in Cu(II)-spiked tap water samples.
