The present work regards the sequential voltammetric determination of Ir(III) and Pb(II) in vegetable environmental matrices. The analytical procedure was verified by the analysis of the standard reference materials: Tomato Leaves NIST-SRM 1573a and Olive Leaves BCR-CRM 062. Precision and accuracy, expressed as relative standard deviation and relative error, respectively, were generally lower than 6 % in all cases, while the limits of detection for each element were lower than 5.23 g kg-1. Once set up on the standard reference materials, the analytical procedure was transferred and applied to laurel leaves sampled in three sites differently influenced by vehicle traffic. A critical comparison with spectroscopic measurements is discussed.

Abstract

The present work regards the sequential voltammetric determination of Ir(III) and Pb(II) in vegetable environmental matrices. The analytical procedure was verified by the analysis of the standard reference materials: Tomato Leaves NIST-SRM 1573a and Olive Leaves BCR-CRM 062. Precision and accuracy, expressed as relative standard deviation and relative error, respectively, were generally lower than 6 % in all cases, while the limits of detection for each element were lower than 5.23 g kg-1. Once set up on the standard reference materials, the analytical procedure was transferred and applied to laurel leaves sampled in three sites differently influenced by vehicle traffic. A critical comparison with spectroscopic measurements is discussed.
