Resumen:
|
Cd and Pb determination in ambient aerosol samples based on SWASV at a Bi film glassy carbon electrode is described. Extremely acid solutions resulting from sample digestion were directly assayed, with sufficient detection limits for testing the fulfilment of air quality regulations. Accuracy was tested on NIST Standard Reference Materials and real aerosol samples, with good recoveries for Pb comparable to ICP-MS results. Cd was not detected, probably due to the combined effects of low Cd and high interfering Zn and Cu contents. The proposed method provides an attractive alternative to ICP-MS with potential applicability for decentralized analysis.
