ISO 11885 Aluminium Test in Water
The ISO 11885 method is a standardized procedure used to determine the concentration of aluminium (Al) in water samples. This test is crucial for ensuring compliance with regulatory standards and assessing the quality of drinking water, industrial processes, and wastewater treatment systems.
Aluminium contamination can arise from various sources including natural waters, corrosion of pipes, and discharge from industries like smelting and chemical production. The ISO 11885 method is widely recognized for its precision and accuracy in quantifying aluminium levels. This service plays a vital role in safeguarding public health by detecting even trace amounts of aluminium that may exceed safe limits.
The testing process involves several key steps. Initially, water samples are collected using appropriate containers to prevent contamination. The samples are then filtered if necessary to remove particulate matter. Following filtration, the sample is diluted according to the ISO 11885 specifications to ensure accurate measurement. Calibration of the analytical instrument is critical and must be performed before each test run.
The analytical method typically employs potentiometric titration or atomic absorption spectrophotometry (AAS). In potentiometric titration, a buffer solution is added to neutralize the pH, followed by adding an EDTA solution. The endpoint is determined using a potentiometric electrode. For AAS, the sample is aspirated into the flame or graphite furnace for atomization and subsequent measurement of aluminium emissions.
The acceptance criteria are strictly defined in ISO 11885. Samples with concentrations above or below specified thresholds require further investigation to identify potential sources of contamination or to confirm compliance with regulatory limits. This service not only provides quantitative results but also offers detailed reports that can be used for decision-making and process optimization.
Compliance with this method ensures reliability in water quality assessment, making it indispensable for industries ranging from beverage manufacturers to environmental protection agencies.
