Abstract
A simple and inexpensive anodic stripping voltammetric procedure for the determination of copper in dolomite, limestone and fly ash extracts is proposed. The method applies an antimony film electrode deposited in situ on a screenprinted graphite substrate. In the optimal conditions: 0.01 M acetate buffer (pH 4.5), 0.01 M KNO3, 0.25 mgL-1 Sb(III) and after 120 s of accumulation at a potential of -1.0 V, the procedure exhibits linear behavior from 4 to 200 μg L-1 Cu(II) with satisfying reproducibility (5%) and an LOD of 0.2 μg L-1
