Overview
ISO 5664:1984 specifies an analytical method for determining ammonium content in water using distillation and titration. Developed by the International Organization for Standardization (ISO), this standard applies to raw, potable, and waste water. The method allows detection of ammonium nitrogen up to 10 mg in a test portion, making it suitable for a diverse range of water quality monitoring scenarios.
By providing a reliable procedure, ISO 5664:1984 helps laboratories and water authorities accurately measure ammonium levels, an important indicator of water quality used for regulatory compliance and environmental monitoring purposes.
Key Topics
Applications
-
Environmental Monitoring
- Used by regulatory bodies to assess nitrogen pollution in surface water, groundwater, and effluents.
- Important for compliance with water quality standards and environmental protection regulations.
-
Drinking Water Quality
- Ensures potable water meets safety criteria for ammonium levels, as high ammonium can indicate contamination.
-
Waste Water Analysis
- Assists in monitoring effluent treatment processes, optimizing operations, and ensuring treated water meets discharge permit requirements.
-
Industrial Process Water
- Used in quality control and pollution prevention in various industries where water recycling and discharge are critical.
Related Standards
To comprehensively manage water quality and laboratory procedures, the following ISO standards are relevant:
- ISO 5663 - Water quality - Sampling techniques.
- ISO 3696 - Water for analytical laboratory use - Specification and test methods.
- ISO 11885 - Water quality - Determination of selected elements by inductively coupled plasma optical emission spectrometry (ICP-OES).
- ISO 7890 (series) - Water quality - Determination of nitrate.
- ISO 14911 - Water quality - Determination of dissolved anions by liquid chromatography.
These standards, alongside ISO 5664:1984, help establish consistent, reliable water analysis methodologies and ensure comparable, accurate data across laboratories and regulatory frameworks.
