Determination of the Common Phenolic Endocrine Disrupting Chemicals in the Water

This paper established a HPLC method of determining two common types of phenols endocrine disrupter (pEDCs) in municipal sewage, surface water and tap water. After the sample is filtered and distilled, the distillate is detected with HPLC-DAD, and quantified in external standard method. In the municipal sewage, surface water and tap water Bisphenol-A (BPA) and 4-octyl phenol (4-OP) are not found. The experiment result shows the linearly dependent coefficient (R2 ) is 0.9914 and 0.9870 respectively, the recovery lies between 89.7-95.6%, the limit of detection is 0.001 (S/N=4.0) and 0.010mg·L-1 (S/N=2.5) respectively. This method has a high separation efficiency and a rapid analysis speed.
