This document describes the extraction from coal by dilute hydrochloric acid and determination of extractable sodium, potassium, calcium, iron and magnesium.
Abstract
Overview
ISO 1952:2025 - Coal - Determination of extractable metals in dilute hydrochloric acid describes a standardized laboratory method to extract and quantify that are extractable from coal using dilute hydrochloric acid. The method is intended for coal quality assessment and research into coal-utilization problems (e.g., fouling and slagging). Extraction is followed by instrumental determination primarily by , with permitted when suitably validated.
