提出了一种用于在线监测自来水中余氯的简单电化学传感器。在本研究中，制造了使用 Pt、Al 或不锈钢工作电极的电位传感器。铂电极和不锈钢电极均表现出高性能。例如，SUS304 不锈钢电极暴露于 1 mg/L 余氯浓度下约 4 分钟内获得 200 mV 响应。评估了 pH 值和溶解氧浓度作为环境因素的影响，Pt 和 SUS316 电极随着这些参数的变化表现出相同的变化。数据表明，适当的电极材料配对可以制造具有紧凑、低功耗、低成本和鲁棒性优点的全固态传感器器件。 (C) 2017 Elsevier B.V. 保留所有权利。
A simple electrochemical sensor for the in-line monitoring of residual chlorine in tap water has been proposed. In this study, potentiometric sensors using either Pt, Al or stainless steel working electrodes were fabricated. Both Pt and stainless steel electrodes exhibited high performance. As an example, a 200 mV response was obtained from SUS304 stainless steel electrode exposed to 1 mg/L residual chlorine concentration within about 4 min. The effects of pH and dissolved oxygen concentration as environmental factors were evaluated, and Pt and SUS316 electrodes showed the same variation with changes in these parameters. The data suggest that the appropriate pairing of electrode materials could allow the fabrication of all-solid-state sensor devices with the advantages of compactness, low power consumption, low cost and robustness.
