A MWCNT-EBP-NA composite film modified GCE was fabricated and characterized.
- •
The GCE modified with the MWCNT-EBP-NA composite film exhibited excellent performance in the analysis of Cd(II) and Pb(II) by SWASV.
- •
The Cd(II) and Pb(II) detection limits of the developed electrode were approximately 0.06 μg/L and 0.08 μg/L, respectively.
- •
Bi/MWCNT-EBP-NA/GCE was successfully used to determine metal ions in soil samples.
