ISO 10304-5 Haloacetic Acids Determination Test in Water
The determination of haloacetic acids (HAAs) in water is crucial to ensure compliance with drinking water regulations worldwide. HAAs are formed during the chlorination process and are among the regulated disinfection by-products (DBPs). ISO 10304-5 provides a standardized method for determining HAAs in water, which is particularly important for maintaining public health.
The test involves several key steps, including sample collection, preparation, and analysis. Samples must be collected from potable water sources, distribution systems, or wastewater treatment plants. Proper sample handling prevents contamination and ensures accurate results. After collection, samples are preserved with nitric acid to prevent further chemical reactions.
Analysis of HAAs is performed using high-performance liquid chromatography (HPLC) equipped with a UV-visible detector and an ion-pairing reversed-phase column. This method allows for the separation and quantification of individual HAA compounds, such as monochloroacetic acid (MCAA), dichloroacetic acid (DCAA), trichloroacetic acid (TCAA), and others.
The test procedure outlined in ISO 10304-5 involves several critical steps:
- Sampling: Collecting water samples from various locations within the distribution system to ensure a representative sample.
- Preservation: Adding nitric acid to maintain stable concentrations of HAAs during storage and transport.
- Preparation: Filtering the preserved samples through 0.45 µm filters to remove particulates that could interfere with analysis.
- Analytical Procedure: Using HPLC with UV-visible detection to separate and quantify individual HAAs based on retention time and peak area.
The precision of this method is demonstrated by its repeatability, which is typically within ±5% for each HAA compound. Accuracy is ensured through the use of certified reference materials (CRMs) and quality control samples. The method can detect HAAs at concentrations as low as 0.1 µg/L.
The importance of this test lies in its role in ensuring that drinking water meets regulatory standards, such as those set by the United States Environmental Protection Agency (EPA) and World Health Organization (WHO). Compliance with these regulations is essential to protect public health from potential adverse effects of HAAs, including liver toxicity, kidney damage, and increased cancer risk.
