Development of a Low-Cost Hemin-Based Dissolved Oxygen Sensor With Anti-Biofouling Coating for Water Monitoring
Abstract
Conventional electrochemical dissolved oxygen (DO) sensors are expensive as they use platinum in their construction. In addition, these sensors biofoul when used in natural or waste water, which leads to reduced sensitivity and variable performance. Here, we solve these problems by: replacing platinum with hemin as the low-cost alternative for electrocatalysing the oxygen reduction reaction and using silicone rubber [poly(dimethylsiloxane) …
