摘要: Abstract The technique most widely used for chromium determination in biological and environmental samples is atomic absorption spectrometry with flame (FAAS) or graphite furnace (GFAAS). In this regard, there are many articles the literature dealing effect of interferences upon solutions different oxidation state. These effects not well established results contradictory. With aim joining all information, we review state art AAS samples. first part paper related sample pretreatment methods proposed natural seawaters, sediments, soils, plant materials, sewage sludges urban particulate matter. second deals instrumental parameters interference which affect measurements by FAAS GFAAS. last presents certified reference materials available quality c...
