Detection of Disinfection By-Products in Tap Water by Solid Phase Microextraction Gas Chromatography Triple Quadrupole Mass Spectrometry
Solid phase microextraction gas chromatography triple quadrupole mass spectrometry (SPME-GC-TQMS) was used to detect the tap water from different areas in Hefei Science Island. It was used to study the existence of partial disinfection by-products (DBPs) in tap water and the relation between DBPs concentration and storage time of tap water in tube. SPME-GC-TQMS was also used to investigate the effectiveness of boiling method for the removal of halogen hydrocarbon disinfection byproduct. The results indicated that tap water in the Science Island contained chloroform, bromodichloromethane, dibromochloromethane and other halogenated hydrocarbon DBPs. In addition, their difference of concentration in tap water from different buildings was up to three times. The longer the storage time of tap water, the lower the concentration of DBPs. The results indicated that most of DBPs in tap water can be effectively removed after boiled. But the chloroform concentration only decreased to 30.2% of the original concentration of tap water.
