Abstract
In this work, ZnO nano particles were synthesized and their characteristics were investigated by scanning electron microscopy and X-ray powder diffraction. ZnO nano particles and a synthesized ionic liquid (1-Methyl-3-butylimidazolium bromide) were applied to modification of carbon paste electrode. Electrochemical behavior of benserazide (BA) was studied at modified electrode. Under optimum pH of 6.0, the relation between oxidation current and concentration of BA was linear in the range of 0.1–430.0μmolL−1 BA. Detection limit of method was calculated to be 0.06μmolL−1 BA. Effects of potential interferences on determination of BA were investigated and proposed method was used for determination of BA in biological samples.
