ISO 17586:2016 specifies a method of extracting trace elements from soil at approximately pH 0,5 using a dilute nitric acid solution. Using this method the potential environmental available trace elements as defined in ISO 17402 is extracted. The method is applicable for all soils and soil like materials.
Abstract
Overview
ISO 17586:2016 - "Soil quality - Extraction of trace elements using dilute nitric acid" specifies a standardized laboratory procedure for extracting the potentially environmentally available trace elements from soils using a dilute nitric acid solution (target pH ≈ 0.5). The method is applicable to all soils and soil‑like materials and yields extracts suitable for sensitive analytical techniques (ICP‑MS, ICP‑OES, AAS) to quantify trace metals for environmental assessment and monitoring.
Key topics and technical requirements
- Extraction chemistry: Use a dilute nitric acid solution of (0.43 ± 0.02) mol·L⁻¹ to achieve an extract pH typically between 0.5 and 1.0 (for highly calcareous soils final pH should be
