dc.description.abstractA highly sensitive electrochemical sensing platform was proposed for trace analysis of Eriochrome Black T in aqueous solutions by adsorptive stripping linear sweep voltammetry based on the open-circuit accumulation of Eriochrome Black T onto the fabricated multi-walled carbon nanotubes modified glassy carbon electrode surface. The proposed methodology was quite linear between 0.1 and 10 µM of Eriochrome Black T concentration with a correlation coefficient of 0.9981. The precision of the technique was acceptable with the relative standard deviations of lower than 13.4% for inter-day assays. In addition, the sensitivity properties of the proposed method were compared with those of the spectrophotometric method, which is frequently used in the literature for Eriochrome Black T analysis. The results showed that the proposed electrochemical sensing platform would be a more sensitive alternative to the existing spectrophotometric techniques. Finally, the methodology was successfully applied to the determination of Eriochrome Black T in a well water spiked at different concentration levels. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group.
