Determination of dissolved oxygen do in water

Webof dissolved oxygen (DO) in a stream or lake is integral to water-quality management. The decay of organic matter in water is measured as biochemical or chemical oxygen demand. Oxygen demand is a measure of the amount of oxidizable substances in a water sample that can lower DO concentrations (Nemerow, 1974; Tchobanoglous and Schroeder, 1985). WebOxygen in water can usually come from the oxygen in the air, and it can also be produced through the photosynthesis of plants in the water. At the same time, there are many factors in the water that consume oxygen, so the oxygen content in the water is unstable, and it needs to be dissolved by a professional solution.
