ISO 15586 Mercury by Atomic Absorption Spectrometry
The ISO 15586 standard specifies a method for determining mercury in water and waste waters using atomic absorption spectrometry. This technique is widely recognized for its precision, accuracy, and reliability in environmental testing.
Mercury contamination is a significant concern due to its toxicity and persistence in the environment. The presence of even trace amounts can have severe ecological impacts and pose risks to human health. Therefore, compliance with regulatory standards like ISO 15586 is crucial for industries handling wastewater or effluents.
The method involves several critical steps starting from sample collection and preparation through to the final analysis by atomic absorption spectrometry (AAS). Proper sampling ensures representative results that reflect actual concentrations in the waste stream. Samples must be stored under controlled conditions before analysis, typically at 4°C or refrigerated.
Once prepared, samples are introduced into an AAS instrument equipped with a hollow-cathode lamp emitting light at specific wavelengths corresponding to mercury atoms. As the sample passes through this chamber, any mercury vaporizes and absorbs some of the incident light, creating a characteristic absorption spectrum. By measuring this absorbed light intensity, analysts can calculate the concentration of mercury in parts per billion (ppb).
For accurate results using ISO 15586, it is essential to follow strict calibration procedures and maintain optimal operating conditions for the AAS equipment. Regular maintenance checks help ensure consistent performance over time.
The standard also provides guidelines on selecting appropriate dilutions based on expected mercury levels in the sample. This ensures that measurements remain within linear range of the instrument, enhancing both accuracy and precision.
Compliance with ISO 15586 is mandated by various environmental regulations worldwide, making it a vital tool for ensuring adherence to legal limits on mercury discharge into receiving waters.
In summary, this method offers reliable quantification of mercury in wastewater samples. Its widespread acceptance makes it an indispensable part of any comprehensive water quality monitoring program aimed at protecting both aquatic ecosystems and public health.
