【 摘 要 】

This paper has tested typical anions including F-, Cl-, NO3-, BrO3-, ClO-, SO42-.in tap water from Xiamen in order to understand the residual status of disinfection byproducts. Ion chromatography is used to analyze anionsconcentrations from residential and industrial zones in six Districts of Xiamen. The results demonstrate that: (1)BrO3-is not detected in all samples, (2) NO3-and SO42-exceed 4.046mg/L and 2.223mg/L, the peakconcentrations are 14.342mg/L and 39.345mg/L, respectively, (3) NO3-and SO42-are quite high in Haicang, Siming and Huli districts, which exceed 14.031mg/L and 36.708mg/L, respectively, (4) Smallerresidual disinfection byproductsare found in the tap water near the industrial areas of Jimei, Tongan and Xiangan Districts compared to other districs, all criteria meet the national standard, which means water quality is in a good condition in these three areas.
