Based on the
chlorine dioxide observations, "there is very clear evidence that there's unusual chlorine chemistry taking place in the north," Sanders told SCIENCE NEWS.
APPLICATION: For pulp bleaching, the use of in-situ peracetic acid generated from TAED and peroxide provides a useful option for debottlenecking mills that have limited
chlorine dioxide capacity.
With respect to taste and odor control, there are a number of studies reporting on the successful use of
chlorine dioxide in the treatment of musty odors, fishy tastes and odors from Mallonmonas, and taste and odor problems associated with Anabaena, Asterionella, Synura, and Vorticella, as well as actinomycetes which are a source of geosmin and 2-methylisoborneol (MIB).|3,4,5~ A 1986 study which compared
chlorine dioxide, chlorine, ozone, and potassium for removal of five specific taste and odor compounds from drinking water found removals ranging from 30 to over 50 percent for practical Cl|O.sub.2~ dosages and contact times.|6~
Chlorine dioxide has also been shown to be effective for treating tastes and odors associated with phenol and phenolic compounds.|7,8,9~
Gaseous
chlorine dioxide did not affect the overall visual quality of the potatoes.
She said: "Starting with a 22.4% solution (as in MMS) and allowing for the stoichiometry suggested, this could produce something in the region of 36g of
chlorine dioxide per litre of water.
Hydrogen peroxide was manufactured by Dinamica PA (35%), whereas product Dioxiplus, employed for
chlorine dioxide, was manufactured by Dioxide.
Cloralstan is a buffered, water-based solution that contains
chlorine dioxide gas in sodium chlorite.
In preliminary research, Bai and his colleagues found that the
chlorine dioxide gas could be released too quickly, which could cause chemical burns on the fruit.
Kahramaa, on its part, assured that the amount of
chlorine dioxide being used for water purification doesn't exceed 0.4 percent per litre.
Target: Chemours/disinfectants, oxone and
chlorine dioxide business lines
Chlorine dioxide (Cl[O.sub.2]) is a strong oxidant widely applied for sterilization, disinfection, and waste-water treatment.
