Development of an all-solid-state residual chlorine sensor for tap water quality monitoring

摘要: Abstract 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 exhibited high performance. As an example, a 200 mV response was obtained from SUS304 electrode exposed to 1 mg/L concentration within about 4 min. The effects pH dissolved oxygen as environmental factors evaluated, SUS316 showed same variation with changes these parameters. data suggest that appropriate pairing materials could allow fabrication all-solid-state devices advantages compactness, low power consumption, cost robustness.
