eng	Dead-End Separation to Isolate and Concentrate Non-Volatile Organic Pollutants from Water	This work studied a concentration technique for non-volatile organic substances in water using dead-end membrane separation. The synthetic estrogen 17-α-ethynylestradiol served as a model analyte. A unique apparatus was used for the procedure, an essential part of which was the MMS Mem Tester, Nitrogen served as the propellant. By selecting a suitable nanofiltration membrane, it was possible to achieve almost 100 % efficiency of isolation and subsequent determination of the test substance in the concentration range of 2.5·10–6 mol·l–1 to 5·10–8 mol·l–1. Analyses were performed by the voltammetric DPV method using anodic oxidation with a BDDE working electrode in Britton-Robinson buffer (BRB, pH 9) in the presence of 33% acetonitrile. The proposed method was applied to the analysis of the surface water.	Dead-end separation, 17-α-Ethynylestradiol, Electrochemical oxidation, Boron-doped diamond electrode
