Soil quality. Parameters for geochemical modelling of leaching and speciation of constituents in soils and materials - Extraction of humic substances from aqueous samples Ingestion-build-264231 This International Standard is applicable1 Scope This part of ISO 12782 specifies a procedure to determine the concentration of humic substances in aqueous samples. These samples may be obtained as such or as eluates from leaching procedures applied to soil or other materials. Other materials also include waste. The content of humic substances can be used as input in geochemical models.
