REDUCTION IN CHEMICAL OXYGEN DEMAND OF OZONATED SUGAR SOLUTIONS BY CHARCOAL

ABSTRACT Sugar solutions at a concentration of 0.10% were subjected to low‐level ozonation, in order to oxidize the solute directly or indirectly to the corresponding aldonic acid. Charcoal adsorption of the monosaccharides was more efficient after ozonation. Adsorption of the disaccharides was, by...

Zusammenfassung:ABSTRACT Sugar solutions at a concentration of 0.10% were subjected to low‐level ozonation, in order to oxidize the solute directly or indirectly to the corresponding aldonic acid. Charcoal adsorption of the monosaccharides was more efficient after ozonation. Adsorption of the disaccharides was, by far, less efficient after ozonation. The chemical oxygen demand of a standard gluconic acid solution was reduced to 10% of its original concentration by charcoal alone.
