There are three main reactive oxygen species: the superoxide anion (O 2 −), hydrogen peroxide (H 2 O 2), and the hydroxyl radical (OH•). The superoxide anion is formed directly from the one-electron reduction of molecular oxygen. [29] Hydrogen peroxide is then formed from the disproportionation of the superoxide anion. This reaction occurs ...
Heterosigma akashiwo is a species of microscopic algae of the class Raphidophyceae. [1] [2] It is a swimming marine alga that episodically forms toxic surface aggregations known as harmful algal bloom. The species name akashiwo is from the Japanese for "red tide". [1]
The Mehler reaction is named after Alan H. Mehler, who, in 1951, presented data to the effect that isolated chloroplasts reduce oxygen to form hydrogen peroxide (H 2 O 2). [1] ...
Greater amounts of oxygen can be provided by contacting the water with pure oxygen or addition of hydrogen peroxide (H 2 O 2) to the water. In some cases, slurries of solid calcium or magnesium peroxide are injected under pressure through soil borings. These solid peroxides react with water releasing H 2 O 2 which then decomposes releasing ...
Hydrogen peroxide (H 2 O 2). It is used, for example, to bleach wood pulp and hair or to prepare other bleaching agents like perborates, percarbonates, peracids, etc. Sodium percarbonate (Na 2 H 3 CO 6), an adduct of hydrogen peroxide and sodium carbonate ("soda ash" or "washing soda", Na 2 CO 3).
In addition, the researchers also pointed out that oxidants such as hydrogen peroxide and sodium percarbonate can cause the rapid death of Ulva australis, thus these chemicals can be used to control the green tide caused by Ulva australis. [20]
