It is produced commercially by electrolysis of seawater and brines. Sodium chloride (NaCl), or common table salt, can be obtained from seaside evaporation pools or mined from underground deposits. Chlorine and its compounds have a large number of everyday uses. Chlorine is used in water ...
(Elements & Compounds) a toxic pungent greenish-yellow gas of the halogen group; the 15th most abundant element in the earth's crust, occurring only in the combined state, mainly in common salt: used in the manufacture of many organic chemicals, in water purification, and as a disinfectant ...
Today, pulp is bleached using an ‘Elemental-Chlorine Free’ (ECF) process and a ‘Totally Chlorine Free’ (TCF) process. We only use TCF because it’s the only process that is 100% free of chlorine and its compounds. Natracare is dedicated to eliminating the risk of any exposure to chl...
47 Chlorine-producing compounds are also used as disinfectants and water-purifying agents. Although it was recognized in the 17th century that heating ammonium chloride and nitric acid together created an irritating gas, chlorine was first described and used as a bleaching agent in the 1770s. In ...
Diverse microorganisms have been associated with fresh produce outbreaks thereby demonstrating the lack of an efficient washing and sanitizing protocol. Several chemical compounds are commercially available, where chlorine and its derivatives are very common, economical, and convenient alternatives. Chlorine-re...

Chlorinated compounds are ubiquitous. However, accumulation of chlorine-containing waste has a negative impact on human health and the environment due to the inapplicability of common disposal methods, such as landfill and incineration. Here we report a
Chlorine is converted between organic and inorganic forms in a biogeochemical cycle [1]. Oxidation and reduction of chlorine produces different inorganic species, including the chlorine oxyanions hypochlorite (ClO−) (and its conjugate acid hypochlorous acid, HOCl), chlorite (ClO2−), chlorate (ClO...
Chlorine does not occur in the elemental state because of its high reactivity. In nature the element occurs mainly as sodium chloride in seawater. Its abundance in seawater is 1.9% by weight. It also exists as chloride in many rocks and minerals such as carnallite (KMgCl3•6H2O) and syl...
