Carbon materials have an extensive usage on many areas of utilization, like healthcare, textile, and electronics, due to unique characteristic features of carbon. Coal tar accepted as primer material by the reasons of economical cost and contains high amounts of carbon. Within the context of the study, graphene nanoribbons (GNR), obtained by chemical oxidation of multi walled carbon nanotubes (MWCNT) and carbon nanotubes, are doped into glass fiber–coal tar mixture. To determine samples’ structural and electrical properties, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), Raman spectroscopy, cyclic voltammetry (CV) and electrochemical impedence spectroscopy (EIS) characterisation methods had been used. The result of characterisations revealed that, sample (GF-CTP-GNR), which produced via graphene nanoribbon doping into glass fiber–coal tar mixture, have existing oxidized carbon in structure and GF-CTP-GNR has more disordered structure compared to other samples. After characterisation processes, produced materials pressed into disc electrodes and observed and tested that, these electrodes can be used to determination of triclosan. Due to obtained data, top performing electrode is determined GF-CTP-GNR among the samples. Real sample analysis has been made with the top performing electrode. Four diffrent tap water were used as real samples, and the precision and accuracy of the method being developed has been tested.
