Abstract:
Objective To know the pollution level of phthalates in Jiulong River source water and the purification efficiency by conventional water treatment processes. Methods The samples of Jiulong River source water and treated water from two waterworks were collected and analyzed with GC-MS during Aug.-Sep.2006. Results Jiulong River had been polluted by phthalates. The prominent phthalates pollutants were dibutyl phthalate (DBP) and diethyl phthalate(DEP). The maximum concentrations reached 17.238 ?g/L and 11.701 ?g/L, respectively. PAEs content in tap-water was lower than the standard limits. Conclusion The conventional water treatment processes, preoxidation, coagulation, sedimentation, filtration and disinfection, could remove phthalates from the drinking water to a certain degree, but the risk of phthalates pollution in drinking water still exists.
