Determination of Copper and Iron in Real Sample of Water and Ethanol Using Square Wave Voltammetry with a Micro/Nano Boron-Doped Diamond Electrode
Abstract Currently, the search for a more economical alternative with adequate selectivity, sensitivity and reproducibility in the determination of metallic ions is important for the development of reliable methodologies for the determination of these contaminants. This work investigates a boron-dop...

| description | Abstract Currently, the search for a more economical alternative with adequate selectivity, sensitivity and reproducibility in the determination of metallic ions is important for the development of reliable methodologies for the determination of these contaminants. This work investigates a boron-doped micro/nano diamond electrode, with different morphology and structure compared to those discussed in the literature, for the detection of copper and iron in aqueous and ethanolic environments. Internal validation of the Square Wave Voltammetry was applied. The methodology was submitted to validation by: selectivity, linearity, precision (interday test), accuracy (percentage of recovery) and detection and quantification limits. The results indicated that this type of electrode showed good response to determinations in aqueous and ethanolic environments, with good selectivity, linearity, accuracy (recovery between 70% and 110%) and precision, presenting the best detection and quantification limits for the aqueous. The methodology using a boron-doped diamond micro/nano electrode was suitable for the determination of copper and iron metals in both matrices. |
