REAL-TIME, ON-LINE ANALYSIS OF HALOACETIC ACID SPECIES AND AMOUNTS THEREOF IN DRINKING WATER SUPPLIES

摘要

Post-column reaction-ion chromatography (PCR-IC) analysis of drinking water samples for quantity measurements and species identification of haloacetic acid contaminants therein is provided. With the necessity to chlorinate drinking water to remove harmful bacteria and other potential toxins, haloacetic acid byproducts are generated that may harm humans after consumption as well. A reliable manner of measuring such drinking water supplies for haloacetic acids at locations far from the source and closer to dispensers is highly desirable. The PCR-IC analysis method of the invention has been found to be nearly as reliable as source measuring methods for the same purpose, but with the versatility to measure for such haloacetic acid contaminants anywhere along the drinking water supply line.
