| الوصف: | The simultaneous electrochemical determination of lead (Pb) and cadmium (Cd) in low-cost jewelry was achieved using differential pulse voltammetry (DPV). The presented voltammetric detection via standard addition shows possible simultaneous analyses of Cd and Pb. The detection limit of 1.13 × 10−4% m m−1 for lead and 1 × 10−3% m m−1 for cadmium were obtained. The recovery rate ranged between 99 and 110% for Cd and 99–105% for Pb. Nine different low-cost jewelry pieces were analysed. Some were purchased from local trade while others were confiscated goods from the police force. |
