Abstract:
Objective To know phthalates(PAEs) pollution in drinking water of Nantong City. Methods With solid phase extraction and gas chromatography-mass spectroscope(GC-MS),main phthalates in drinking water were determined. Results Phthalates could be detected in all the source water, product water and tap water samples, mainly were di-n-butyl phthalate(DBP) and di(2-ethylhexyl) phthalate(DEHP),ranged from 1.25 to 4.59 ?g/L and from 0.97 to 3.57 ?g/L respectively. PAEs levels in product water were less than those in source water. The highest removal rate of DBP was 50%. PAEs levels in tap water were higher than those in product water,sometimes even higher than those in source water. Conclusion PAEs can not be effectively removed from source water after general water treatment process.
