The Halogen Demand of Commercial Beverage Powders, Drinks and Their Constituents

摘要

The chlorine and iodine demands of commercially available synthetic beverage mixes and drinks were determined using an amperometric titrator. The major components of these drinks were also assayed individually for their halogen demand. All commercially available drinks were found to exert extremely high halogen demand to the point where they would neutralize most of the chlorine and iodine present, leaving no residuals for disinfection. The components of these drinks varied in their ability to react with chlorine and iodine. Based on these results, four in-house drink formulations were developed with components having little or no halogen demand. (Author)
