Abstract

A novel anion-selective electrode for salicylate ion with new ionophore was designed based on modified carbon paste electrode with multi walled carbon nanotubes (MWCNTs). Electrode made was evaluated for electrochemical studies using potentiometric and impedance techniques and results compared with together. The results of the potentiometric method using modified carbon paste electrode showed that the prepared electrode has a Nernstian slope 60. 1± 0. 1 mV in concentrations measurement range 1. 0×10-7-1. 0×10-1 M, the detection limit 5. 4×10-8, with pH range of 3. 5-9. 3, while using the impedance technique, the concentration measurement range increased to 1. 0×10-9-1. 0×10-1 M, pH range increased to 3. 8-10. 7 and the detection limit decreased to 4. 3×10-10 M.
