Sensitivity of an integrating differential pulse polarograph to interfering signals

Research output: Contribution to journalArticlepeer-review

3 Scopus citations


A model for error response in differential pulse anodic stripping voltammetry in the presence of a deterministic signal is proposed and successfully applied to predict the error in a practical instrumentation system. It is demonstrated that the system is efficient in rejecting 50 Hz and its harmonics, but produces a relatively large error for interfering signals of low frequencies. The sensitivity of the method in the determination of Cd(II) is estimated theoretically and verified experimentally for the polarograph studied.
