This accounts for its bleaching action, since many colored organic substances owe their color to compounds with such bonds. [ citation needed ] The extensive reactivity of chlorine is also responsible for its broad antimicrobial effect, since it can destroy or denature many proteins and other chemicals that are essential for microbes' metabolism .
"Bleaching powder" usually refers to a formulation containing calcium hypochlorite. [citation needed] Oxidizing bleaching agents that do not contain chlorine are usually based on peroxides, such as hydrogen peroxide, sodium percarbonate, and sodium perborate. These bleaches are called "non-chlorine bleach", "oxygen bleach", or "color-safe bleach".
Most TCF pulp is produced in Sweden and Finland for sale in Germany, [31] all markets with a high level of environmental awareness. In 1999, TCF pulp represented 25% of the European market. [32] TCF bleaching, by removing chlorine from the process, reduces chlorinated organic compounds to background levels in pulp-mill effluent. [33]
Chlorine dioxide can be used for air disinfection [33] and was the principal agent used in the decontamination of buildings in the United States after the 2001 anthrax attacks. [34] After the disaster of Hurricane Katrina in New Orleans , Louisiana , and the surrounding Gulf Coast, chlorine dioxide was used to eradicate dangerous mold from ...
Calcium hypochlorite is an inorganic compound with chemical formula Ca(Cl O) 2, also written as Ca(OCl) 2.It is a white solid, although commercial samples appear yellow. It strongly smells of chlorine, owing to its slow decomposition in moist air.
Chemical pulping involves dissolving lignin in order to extract the cellulose from the wood fiber. The different processes of chemical pulping include the Kraft process, which uses caustic soda and sodium sulfide and is the most common; alternatively, the use of sulfurous acid is known as the sulfite process, the neutral sulfite semichemical is treated as a third process separate from sulfite ...
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.
It is a chlorine releasing bleaching agent widely used to whiten clothes and remove stains, as a disinfectant to kill germs, and for several other uses. While the term has had this meaning for a long time, it may now be applied more generically to any liquid bleaching agent for laundry, irrespective of composition, such as peroxide-based bleaches.
