The objective of this research was to determine whether aqueous chlorine and chlorine dioxide react with activated carbon, or with compounds adsorbed on activated carbon, to produce compounds that would not form in the absence of activated carbon. Resorcinol reacted with chlorine and chlorine dioxide at pH 7 in dilute aqueous solution and in the presence of granular activated carbon (GAC) to produce numerous chlorinated compounds. Major products included chlororesorcinols and various chlorinated eduevazquez.com by: Reaction of activated carbon with aqueous chlorine and chlorine dioxide / By Vernon L.

Reactions of chlorine and chlorine dioxide with resorcinol in aqueous solution and adsorbed on granular activated carbon. Water Research , 21 (7), Cited by: The chemical reactions of chlorine dioxide are much more specific and selective than those of chlorine and, as a consequence, it has a lower demand by water and does not produce as many by-products. However, chlorine dioxide is not an ideal oxidant either, because it reacts with various inorganic and organic aquatic compounds to produce a variety of eduevazquez.com by: 9. In the presence of ammonia, prechlorination in drinking water treatment results in contact of combined chlorine (monochloramine) with activated carbon, which is used to remove organic compounds from water. Monochloramine reacts very slowly with phenolic compounds in aqueous solution, giving low yields of chlorinated eduevazquez.com by:
Dechlorination involves a chemical reaction of the activated carbon’s surface being oxidized by chlorine. There are reactions when hypochlorous acid and hypochlorite ion react with activated carbon. Organic halogen concentrations have been shown to increase with increasing chlorine dioxide dose, but are much lower than those observed when chlorine is applied. Aldehydes have been detected as apparent by-products of chlorine dioxide oxidation reactions in . An activated carbon has been oxidized with wt% aqueous solutions of sodium - dichlororisocyanurate (DCI) to introduce oxygen and chlorine surface groups by chemisorption; the formation of chlorine surface groups is important whenthe concentration of DCI is high, the modification of the microporosity being small. "Aqueous chlorine" is a misleading term because the active form of chlorine that is present in treated water and wastewater is not the gaseous chlorine molecule (Cl 2) but, rather, a hydrolysis product, hypochlorous acid (HOCl), which is formed from the reaction between the chlorine molecule and water.
