Abstract

Background. Environmental contamination with heavy metals poses a threat to human health and water supplies. Purpose. To develop a modified electrochemical sensor for the determination of As(III) ions using stripping voltammetry. Methodology: A glassy carbon electrode was fabricated, and ion analysis was performed using stripping voltammetry in acetate buffer. Originality: The detection limit for metal ions is 8 ppt, the quantitative limit is 24 ppt, and the method is stable for up to 150 cycles. Findings. Linearity was established in the range of 0.5-10 ppb (R² = 0.985), the detection limit was 8 ppt, and the RSD was 0.08%. The stability and selectivity of the sensor were confirmed.
