Dissolved Oxygen

2022
Abstract This chapter discusses the chemistry of dissolved oxygen (DO), which plays a critical role in regulating the redox chemistry of natural waters. DO concentrations are controlled by a range of chemical and biological redox processes and by physical factors that affect O2 solubility and transfer rates across the air-water interface.

DOxy: Dissolved Oxygen Monitoring

2020 IEEE Global Humanitarian Technology Conference (GHTC), 2020
Dissolved Oxygen (DO) in water is the enabler of all marine life. As low oxygen levels are the first sign of contamination and distress in bodies of water, measuring its levels are the first step in discovery and preservation efforts. Furthermore, fish farms, aquariums, and other aquaculture are in need of continued dissolved oxygen monitoring and ...

Determination of dissolved oxygen in water

Talanta, 1978
Dissolved oxygen in water is determined by its oxidation of manganese(II) to manganese(III) in alkaline medium and formation of the red manganese(III) ethylenediaminetetra-acetic acid complex on acidification to pH 4. The range of determination is 7-3160 mug of oxygen in a final volume of 500 ml.

Interaction of positronium with dissolved oxygen in liquids

Physical Chemistry Chemical Physics, 2020
The interaction of positronium with molecular oxygen dissolved in liquids is experimentally investigated. A computer software has been developed for fitting the positron annihilation lifetime spectra using parameters with clear physical meaning.
