Abstract
The recovery of 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX) from granular activated carbon (GAC)/distilled water by adsorption on XAD-8 resin was approximately 3-fold greater than on XAD-2 resin. When chlorine was added at levels ranging from 0-3 mg/L, the percent of MX recovered by XAD adsorption decreased as the concentration of chlorine increased. Using concentrations of MX which allowed direct measurement of its mutagenicity, a time-dependent decrease in mutagenicity was observed, which was enhanced by the presence of chlorine. The concentration of MX as determined by UV absorbance also decreased in the presence of chlorine, at a rate which increased with increasing chlorine concentration. These results suggest that the level of MX present in tap water is dependent not only on the amount of MX produced by the chlorination of humic substances and other precursors but also on the rate of degradation with residual chlorine.
