چکیده انگلیسی
A new method for determination of methyldopa in the presence of folic acid has been described in this work. This method is based on modification of carbon paste electrode with NiO nanoparticles and an ionic liquid (1-Butyl-3-methylimidazolium hexafluorophosphate). Electrochemical studies showed that on the surface of modified electrode, oxidation current of methyldopa has been enhanced and shifted to negative potentials. The fabricated electrode exhibited a linear response to concentration of methyldopa from 0.1 to 700.0 μmol Lâ1. The sensitivity of the modified electrode to methyldopa not changed in the presence of folic acid and simultaneous or independent measurements of them are possible. The performance of proposed method was investigated by determination of methyldopa in real samples.
