摘要：

Dihaloacetonitriles (DHAN) are formed during chlorine disinfection of drinking water, together with the better known and more frequently measured trihalomethanes (THM). Nine Dutch drinking waters were analyzed for DHANs and THMs. For this analysis we developed a method, using a thick-film capillary column, that gave a good separation and detection limits lower than 0.04 and 0.1 μg/l for DHANs and THMs respectively. All chlorinated drinking waters have been found to contain DHANs (range 0.04-1.05 μg/l) and THMs (range 3.1-49.5 μg/l). In most cases the brominated DHANs and THMs were higher in concentration than the chlorinated ones. The average DHAN concentration was about 5% of the average THM concentration and there was a reasonable correlation between the DHAN and THM concentrations. © 1990.
