Modification of Multiwalled Carbon Nanotubes by Dipyridile Amine for Potentiometric Determination of Lead(II) Ions in Environmental Samples
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...
