Trichloroisocyanuric Acid (TCCA) may be added to the aqueous solution

Trichloroisocyanuric Acid (TCCA) may be added to the aqueous solution of the soluble iodide salt to form in situ aqueous iodine. The iodine may then bind to the iodide at the resin active site to form the iodinated resin, as described herein. According to these embodiments, the iodinated resin may then be removed from the reaction medium and may be used as a part of a water treatment system.
A concentrated aqueous iodine solution (250-300 ppm) is made by reacting in situ a stoichiometric ratio of KI (aq) with a chlorine source, such as Trichloroisocyanuric Acid (TCCA). The iodine solution is passed through a bed of the used iodinated resin in need of regeneration. Sufficient iodine solution is passed through the resin until the resin displays an activity about equal to the activity of new iodinated resin.
Jinxi Chemical company has developed Trichloroisocyanuric Acid (TCCA) product, three indicators are in line with standards, the product can be used in food processing and drinking water disinfection; it can also has good results in sericulture industry and rice seed disinfection, cotton and chemical fiber fabric bleaching, deodorization and decolorization aspects of shrink-proof wool and household chemicals. The production process is simple, and can access to significant economic benefits.
