The free radicals generated by this process engage in secondary reactions. For example, the hydroxyl is a powerful, non-selective oxidant. [6] Oxidation of an organic compound by Fenton's reagent is rapid and exothermic and results in the oxidation of contaminants to primarily carbon dioxide and water.
Hydrogen peroxide is a chemical compound with the formula H 2 O 2.In its pure form, it is a very pale blue [5] liquid that is slightly more viscous than water.It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3%–6% by weight) in water for consumer use and in higher concentrations for industrial use.
The hydrogen peroxide accumulates as sump product. The anthraquinone acts as a catalyst, the overall reaction equation is therefore: H 2 + O 2 → H 2 O 2. If ozone is used instead of oxygen, dihydrogen trioxide can be produced by this method. [4]
Hydroxyl radicals are produced with the help of one or more primary oxidants (e.g. ozone, hydrogen peroxide, oxygen) and/or energy sources (e.g. ultraviolet light) or catalysts (e.g. titanium dioxide). Precise, pre-programmed dosages, sequences and combinations of these reagents are applied in order to obtain a maximum •OH yield.
The FOX reagent, or ferrous oxidation−xylenol orange, is used to measure levels of hydrogen peroxide in biological systems. [1] The reagent is incubated with the sample and absorbance of the product form after a series of oxidation reactions is then measured at a wavelength of 560 nm.
Peroxide fusion is used to prepare samples for inductively coupled plasma (ICP), atomic absorption (AA) analysis and wet chemistry. Sodium peroxide (Na 2 O 2) is used to oxidize the sample that becomes soluble in a diluted acid solution. This method allows complete dissolution of numerous refractory compounds like chromite, magnetite, ilmenite ...
The Trinder glucose activity test is a diagnostic test used in medicine to determine the presence of glucose or glucose oxidase.The test employs the Trinder reagent, and is a colour change test resulting from the Trinder reaction.
The Dakin oxidation. The Dakin oxidation (or Dakin reaction) is an organic redox reaction in which an ortho- or para-hydroxylated phenyl aldehyde (2-hydroxybenzaldehyde or 4-hydroxybenzaldehyde) or ketone reacts with hydrogen peroxide (H 2 O 2) in base to form a benzenediol and a carboxylate.
