چکیده انگلیسی
The methodology uses solid-phase extraction, followed by high performance liquid chromatography coupled to tandem mass spectrometry using an electrospray (ESI) interface operating in positive ion mode (LC-ESI-MS/MS). The extraction was made with 200Â mg, 6Â mL OASIS HLB® cartridges. Recoveries for the selected compounds were in the 67-97% range for all the considered analytes. The method was employed for environmental monitoring. Samples of river water and wastewater collected over a 4-month period were analyzed with the developed procedure. Results showed the presence of isoflavones in most of the samples analyzed. Average concentration of target analytes found in wastewater sewage treatment plant influent ranged from 454 to 12Â ng/L. In effluent water and river water the analytes were present at lower concentration.
