Abstract EN
A carbon paste electrode was modified by dipyridile amine functionalized multiwalled carbon nanotubes for determination of trace amounts of lead(II) ions.
The electrode composition was graphite powder 70%, paraffin 23%, and dipyridile amine modified MWCNTs 7% (W/W).
The linear range for lead(II) was 9.5 × 10−8 to 2.5 × 10−3 mol L−1, and the limit of detection was obtained 7.0 × 10−8 mol L−1.
The lifetime of the electrode was ten weeks, and a fast response time was observed.
The electrode was used for determination of trace amounts of Pb(II) ions in real samples and standard reference materials of water, soil, and plant.
