Описание (английский):

ISO 12914:2012 specifies a method for microwave-assisted extraction of elements from samples using aqua regia as the extraction solution for the determination of elements. This method is applicable to all types of soil and soil material.

Abstract

Overview

Key Topics

Microwave-Assisted Extraction: The method uses closed-vessel microwave heating to speed up and standardize the extraction process, ensuring optimal temperature control and safety during digestion.
Aqua Regia Extraction: Aqua regia, a mixture of nitric and hydrochloric acid, operationally defines the fraction of elements that can be dissolved for analysis. This method does not extract all elements, particularly from refractory phases.
Safety Considerations: Due to the use of strong corrosive reagents and high temperatures/pressures, the standard outlines stringent safety and equipment requirements to minimize risks such as toxic fumes and possible explosions.
Sample Handling & Preparation: Comprehensive guidance is provided for representative soil sampling, pre-treatment (including drying, grinding, and particle size reduction), and preparation steps essential for accurate analytical results.
Quality Control: The standard emphasizes the use of control samples and blank tests to monitor extraction performance and ensure analytical integrity.

Applications

The extraction method prescribed in SIST ISO 12914:2019 has a broad range of practical applications in environmental and soil science, including:

Environmental Site Assessment: Determines the presence and concentration of potentially hazardous elements in contaminated or remediated soils.
Agriculture and Land Use: Assesses nutrient and contaminant levels for sustainable agriculture and land management.
Regulatory Compliance: Supports compliance with local, national, and international regulations that require standardized soil testing procedures for heavy metals and other elements.
Research and Development: Provides a reproducible method for academic and industrial research into soil chemistry, environmental impact, and biogeochemical cycles.
Laboratory Accreditation: Adoption of ISO 12914 supports laboratory accreditation by ensuring procedures align with internationally accepted best practices.

Related Standards

SIST ISO 12914:2019 references and complements several other notable international standards in soil quality and analytical procedures:

ISO 3696: Water for analytical laboratory use - Specification and test methods
ISO 10381-1: Soil quality - Sampling - Guidance on the design of sampling programmes
ISO 11464: Soil quality - Pretreatment of samples for physico-chemical analysis
ISO 11465: Soil quality - Determination of dry matter and water content by gravimetric method
ISO 18512: Soil quality - Guidance on long and short term storage of soil samples

Additionally, related methods from the US EPA (Methods 3015, 3051, and 3052) provide further context for acid digestion procedures in environmental samples.

By utilizing SIST ISO 12914:2019 for soil sample extraction and elemental determination, stakeholders benefit from standardized procedures that foster comparability of data, improve laboratory safety, and support compliance with environmental and quality management requirements. For reliable soil quality analysis and elemental profiling, adherence to this international standard is essential.
