Abstract:

A new functionalized composites (PPy/c-MWNT) by carboxylic multiwalled carbon nanotube (c-MWNT) with polypyrrole (PPy) was studied. PPy/c-MWNT modified glassy carbon electrode (PPy/c-MWNT/GCE) for determination of Cd2+ and Pb2+ was described by cyclic voltammetry, electrochemical impedance spectroscopy, and anodic stripping voltammetry (ASV). PPy/c-MWNT/GCE greatly improved the sensitivity of determining Cd2+ and Pb2+. The striping peak currents changed linearly with the concentration of Cd2+ from 1.0×10-4 to 2.0×10-7 mol/L for an accumulation time of 400 s, and Pb2+ from 1.0×10-4 to 1.0×10-7 mol/L. The high sensitivity, selectivity, and stability of the PPy/c-MWNT/GCE demonstrated its practical application for a simple, rapid and economical determination of trace level of Cd2+ and Pb2+ in water samples
