摘要：
The barium hydrogen phosphate modified carbon paste electrode (BHP-CPE) was prepared as an electrochemical sensor. Its propensity towards the simultaneous determination of Cd(II) and Pb(II) has been demonstrated with differential pulse anodic stripping voltammetry (DPASV) in the potential window between -1.2 V to -0.4 V. Important operational parameters such as pH of the solution, deposition potential and deposition time have been optimized. Under the optimized conditions, calibration curves were linear in the concentration range 1 x 10(-8) to 8 x 10(-8) M on BHP-CPE and 1 x 10(-8) to 5 x 10(-8) M on Nafion-BHP-CPE. Experiments disclosed that BHP-CPE and Nafion-BHP-CPE exhibit good performance for the simultaneous determination of Cd(II) and Pb(II).
