Determination of Total Chromium in Marine Sediments by Flameless Atomic Absorption Spectrophotometry: Reference Methods For Marine Pollution Studies No. 31

This reference method describes the determination of total chromium in marine sediments by flameless atomic absorption spectrophotometry after the extraction of chromium by acid leaching. An aliquot of sample is digested in a nitric/perchloric/hydrofluoric acid mixture in a Teflon beaker, and the total chromium determined by flameless atomic absorption at 357.9 nm wavelength using a deuterium background corrector.
