Abstract
A high sensitive electrochemical nanostructure sensor based on NiO/graphene oxide nanocomposite-ionic liquids (1-methyl-3-butylimidazolium bromide; 1M3BIB) modified carbon paste (NiO/GO/1M3BIB/CPE) electrode
has been developed for trace analysis of sulfamethoxazole (SMTZ). NiO/GO was synthesized by co-precipitation
method and characterized with different methods such as scanning electron microscopy (SEM) and X-ray diffraction (XRD). The electrochemical response was found to be linearly proportional to SMTZ concentration in the
range from 0.08–550μMwitharegressioncoefficient of 0.9935 and a detection limit of 0.04μM. The novel sensor
has been successfully applied for the assay of SMTZ in pharmaceutical and biological samples.
