Complete Solid State Dissolved Oxygen Sensor Using Hemin Electrocatalyst and Palladium-Reusable Reference Electrode

Dissolved oxygen (DO) is essential for aquatic life, but is consumed during the decomposition process of the organic matter in water. It is used as a primary indicator of water quality, and is also crucial for the efficiency of the waste water treatment process. Hence, a sensitive, long term reliable, in-line DO sensor is essential for sustainability of water ecosystems and management of water resources. This paper introduces a low-cost, …
