In this method, initially, sodium chloride was filled into a syringe and a mixture of water sample and acetonitrile was driven to pass through the syringe. Due to salting-out effect, fine droplets of acetonitrile went up through the remaining mixture and aggregated as a separated layer on the top. Then, the collected organic phase (acetonitrile) was removed with a syringe and mixed with carbon tetrachloride (extraction solvent). In the second step, the mixed organic phase was rapidly injected into 5\u00a0mL of distilled water to further enrich the analytes. Good linearity was obtained in the concentration range of 2.0~200\u00a0ng\/mL for diethylstilbestrol (DES) and 8.0~200\u00a0ng\/mL for octylphenol (OP), respectively. Limits of detection were 0.09\u00a0ng\/mL for DES and 0.20\u00a0ng\/mL for OP, respectively. Relative standard deviations for intra- and inter-day precisions were less than 2.1 and 3.1%, respectively. Finally, the established method was successfully applied to determine DES and OP in river water, well water, bottled water and campus drinking water samples with recoveries in the range from 81.0 to 105.9%.<\/jats:p>","DOI":"10.1093\/chromsci\/bmz080","type":"journal-article","created":{"date-parts":[[2019,8,30]],"date-time":"2019-08-30T19:25:43Z","timestamp":1567193143000},"page":"171-177","source":"Crossref","is-referenced-by-count":11,"title":["Combination
