Determination of Dissolved Oxygen

The amount of oxygen dissolved in water is called dissolved oxygen. The amount of oxygen in fresh water is 14.6 mg/L at 1 atm pressure and 0oC. Aquatic life and ecosystem are determined by the amount of dissolved oxygen in the water. In general, the factors affecting the amount of dissolved oxygen in water can be listed as follows: stagnation, depth, temperature, increase in the presence of minerals and pollutants in the water.

Determination of Dissolved Oxygen in Water is an important test parameter for water pollution control activities and controls to be made in water treatment plants. Dissolved oxygen determination is generally carried out using two different methods.

Winkler or iodometric method
Electrometric method using membrane electrodes

“Determination of Dissolved Oxygen” is carried out in accredited and authorized water analysis laboratories for sampling and testing and evaluation of water in terms of quality and pollution.
