Indirect Differential Pulse Voltammetric Determination of Aluminum by a Pyrocatechol Violet-Modified Electrode
摘要:
A PCV-modified electrode was simply prepared by dip-coating a pyrolytic graphite electrode in a NaAc-HAc buffer solution of PCV.The peak currents of differential pulse voltammograms (DPV) decrease with the addition of Al and the peak potentials remain the same.The decreasing of △ip, is linear with Al concentration in the range of 1×10-8~ 1×10-7 mol/L.The detection limit is 5 ×10-9 mol/L and the relative standard deviation for 4×10-8 mol/L Al is 2.9% (n=8).No serious interference was found.The determination of Al in water samples is reported.
