Overview
SIST EN 26777:1996 specifies a standardized method for the determination of nitrite concentration in potable, raw, and waste water. Aligned with ISO 6777:1984, this water quality standard sets out a molecular absorption spectrometric method to ensure accurate and reliable detection of nitrite levels. The method is widely applicable in environmental monitoring and water treatment, supporting compliance with regulatory requirements for water safety and pollution control.
Key Topics
Applications
-
Environmental Monitoring
- Routine analysis of natural water, treated drinking water, and wastewater to assess nitrite contamination, an important indicator of nitrogen pollution and water quality.
-
Water Treatment Facilities
- Quality control of treatment processes to verify the removal of nitrite and ensure regulatory compliance.
-
Regulatory and Compliance Testing
- Used by laboratories and government agencies for statutory monitoring, reporting, and verification of water safety standards.
-
Research and Development
- Supports scientific studies on water pollution, ecological health, and the effectiveness of remediation technologies.
-
Industrial and Municipal Water Testing
- Regular monitoring by industries and municipalities to manage effluent quality and operational safety.
