| Abstract: | The voltammetric performance of an in situ plated antimony film screen-printed carbon electrode in hydrochloric acid, acetate buffer, and tartrate buffer was evaluated for the detection of copper(II) with differential pulse anodic stripping voltammetry. The tartrate buffer was superior, providing high sensitivity and good separation of copper and antimony stripping peaks. The analytical conditions for the determination of copper(II) were optimized. The detection limit was estimated to be 0.14?µg?L?1 copper(II) and the relative standard deviation for 2.5?µg?L?1 copper(II) was 3%. The applicability of the method was illustrated by the analysis of soil conditioner samples. |
