Comparison of nitric acid and aqua regia as extractants for heavy metals in soil samples

A comparison of extraction abilities of nitric acid alone (HNO3) and aqua regia in one-step microwave enhanced digestion procedure is presented in this communication. The certified reference material for soil MetranalTM 33 (Analytika, Czech Republic) as a model soil sample was used. The measurements of the selected elements were done by means of ICP-AES. The results obtained in this research suggest that both tested reagents display similar extraction abilities toward heavy metals that are usually analyzed in soils.
