摘要：
In this work, we suggested a carbon paste electrode improved with 1-methyl-3-octylimidazolium tetrafluoroborate (1-M-3-OITFB) and ZnO/CNTs nanocomposite (1-M-3-OITFB/ZnO/CNTs/CPE) for electrochemical determination of raloxifene (RXF) as a non-steroidal selective estrogen receptor regulator. The cyclic and differential pulse voltammetric methods were apply for investigation of RXF electrochemical response at a surface of 1-M-3-OITFB/ZnO/CNTs/CPE. Under the best experimental conditions, the 1-M-3-OITFB/ZnO/CNTs/CPE showed a wide linear dynamic range of 0.08 - 400.0 mu M. We detected a detection limit of 0.04 mu M for RXF analysis using differential pulse voltammetric method (DPV). The 1-M-3-OITFB/ZnO/CNTs/CPE showed high performance ability to RXF analysis in trace amounts on pharmaceutical and clinical preparations. (C) 2017 Elsevier B.V. All rights reserved.
