  2. Adsorbable organic halides - Wikipedia

    en.wikipedia.org/wiki/Adsorbable_organic_halides

    Adsorbable organic halides (AOX) is a measure of the organic halogen load at a sampling site such as soil from a land fill, water, or sewage waste. [1] The procedure measures chlorine, bromine, and iodine as equivalent halogens, but does not measure fluorine levels in the sample.

  3. Chlorine-releasing compounds - Wikipedia

    en.wikipedia.org/wiki/Chlorine-releasing_compounds

    Chlorine-releasing compounds, also known as chlorine base compounds, is jargon to describe certain chlorine-containing substances that are used as disinfectants and bleaches. They include the following chemicals: sodium hypochlorite (active agent in bleach ), chloramine , halazone , and sodium dichloroisocyanurate . [ 2 ]

  4. Free-radical halogenation - Wikipedia

    en.wikipedia.org/wiki/Free-radical_halogenation

    The relative rates at which different halogens react vary considerably: [citation needed] fluorine (108) > chlorine (1) > bromine (7 × 10 −11) > iodine (2 × 10 −22).. Radical fluorination with the pure element is difficult to control and highly exothermic; care must be taken to prevent an explosion or a runaway reaction.

    2, portlandite) produced by Portland cement hydration in concrete to form calcium carbonate (CaCO 3) while releasing a water molecule in the following reaction: CO 2 + Ca(OH) 2 → CaCO 3 + H 2 O. Exception made of the water molecule, the carbonation reaction is essentially the reverse of the process of calcination of limestone taking place in ...

  6. Halogenation - Wikipedia

    en.wikipedia.org/wiki/Halogenation

    Following the usual trend, bromine is less reactive and iodine least of all. Of the many reactions possible, illustrative is the formation of gold(III) chloride by the chlorination of gold. The chlorination of metals is usually not very important industrially since the chlorides are more easily made from the oxides and hydrogen chloride.

    Still, liquid bleach may nonetheless safely be used for short-term emergency water disinfection. The EPA recommends two drops of 8.25% sodium hypochlorite solution (regular, unscented chlorine bleach) mixed per one quart/liter of water and leave to stand covered for 30 to 60 minutes. Two drops of 5% solution also suffices.

  8. Haloform reaction - Wikipedia

    en.wikipedia.org/wiki/Haloform_reaction

    In chemistry, the haloform reaction (also referred to as the Lieben haloform reaction) is a chemical reaction in which a haloform (CHX 3, where X is a halogen) is produced by the exhaustive halogenation of an acetyl group (R−C(=O)CH 3, where R can be either a hydrogen atom, an alkyl or an aryl group), in the presence of a base.

  9. Water purification - Wikipedia

    en.wikipedia.org/wiki/Water_purification

    Chlorine is a strong oxidant that rapidly kills many harmful micro-organisms. Because chlorine is a toxic gas, there is a danger of a release associated with its use. This problem is avoided by the use of sodium hypochlorite, which is a relatively inexpensive solution used in household bleach that releases free chlorine when dissolved in water ...
