Water quality; Evaluation in an aqueous medium of the "ultimate" aerobic biodegradability of organic compounds; Method by analysis of dissolved organic carbon (DOC)

This international document outlines a standardized method for the analysis of dissolved organic carbon in water samples containing organic compounds. The procedure provides a systematic approach to estimate the carbon content within aqueous media, which is essential for assessing water quality and monitoring organic pollutants. It specifies the necessary equipment, reagents, and operational steps to ensure accurate and reproducible results across different laboratories. The methodology focuses on the complete oxidation of organic carbon followed by the measurement of the produced carbon dioxide, enabling quantification of the total dissolved organic carbon present. By adhering to these defined protocols, users can generate consistent data for environmental assessments, water treatment processes, and regulatory compliance. The text describes the analytical principles and practical guidelines required to execute the analysis effectively, ensuring that measurements reflect the true organic carbon load in the medium under investigation. This framework supports uniform practices in the field of water analysis without implying specific performance outcomes or regulatory mandates.
