Abstract

ISO 11047:1998 - Overview

ISO 11047:1998 defines standardized laboratory methods for determining trace heavy metals in soils - specifically cadmium (Cd), chromium (Cr), cobalt (Co), copper (Cu), lead (Pb), manganese (Mn), nickel (Ni) and zinc (Zn) - using atomic absorption spectrometry (AAS) on aqua regia extracts. The standard describes two analytical routes:

Method A: Flame atomic absorption spectrometry (flame AAS) for higher concentration ranges
Method B: Electrothermal atomic absorption spectrometry (ETAAS) for lower concentrations

The document emphasizes safety and competent operation, and links the extraction step to ISO 11466 (aqua regia extraction).

Key topics and technical requirements

Elements covered: Cd, Cr, Co, Cu, Pb, Mn, Ni, Zn (in aqua regia extracts of soil).
Method selection criteria: Indicative concentration thresholds guide whether to use flame AAS or electrothermal AAS (e.g., Cd >2 mg/kg for flame AAS;
