Description
Summary:The trace metals (Cd, Cu, Pb, Zn, Ni, and Fe) content of certified reference marine sediments PACS-2 and PACS-3 were determined by flame atomic absorption spectrometry. This study aims to ensure the accuracy of a method. The reference sediments are digested with methods 3050B (nitric acid, hydrogen peroxide, hydrochloric acid). Data were collected within seven consecutive years from 2013-2019. The results showed that the percentage recovery of five metals ranged from 87%-113% in PACS-2 and 81%-107% in PACS-3, based on the certified values. This study suggests that acid digestion provides a robust method for metals analysis in the sediment sample.
