The objectives of this powerpoint presentation on disinfection byproduct (DBP) analysis in chlorinated reverse osmosis (RO) concentrates included:
adaptation of analytical methods for 8 priority DBPs,
matrix effect;
stability of the DBPs over the course of holding time experiments;
effectiveness and potential application of the methods developed
for chlorinated RO concentrates; and,
comparison with those used in analysis of U.S. drinking waters
U.S. Nationwide Study (Weinberg et al., 2002, Krasner et al., 2006). Conclusions of the study included:
DBP analyses in complex matrix achieved with high degree of QC
using standard addition or external calibration, and matrix dilution;
matrix effect correlates with K<sub>ow</sub>;
some DBPs undergo more rapid loss during sample preservation and
holding than others;
multiple DBP groups quantified in the chlorinated RO concentrates at
levels not observed in full-scale drinking water treatment; and,
RO concentration permitted observation of yet additional DBPs not
targeted in this study. Includes tables, figures.
