ASTM D5673 Indium Test in Water
The ASTM D5673 method is a standardized procedure used to determine the concentration of indium in water samples. This test is particularly important for monitoring environmental and industrial effluents where trace amounts of indium can accumulate, affecting both aquatic ecosystems and human health.
Indium is a soft, silvery metal with unique properties that make it valuable in various industries, including electronics and semiconductor manufacturing. However, its presence in water bodies at elevated levels can pose risks to both the environment and public health. Therefore, accurate measurement of indium concentration in water is crucial for regulatory compliance and environmental protection.
The ASTM D5673 method involves several steps that ensure precise results. Initially, a water sample is prepared by filtering or diluting it if necessary. The filtered sample is then treated with nitric acid to ensure all indium compounds are dissolved into the aqueous phase. Subsequently, the solution is analyzed using atomic absorption spectrophotometry (AAS), which provides a sensitive and accurate measurement of indium concentration.
The standard specifies strict quality control measures during sample preparation and analysis. These include calibration checks using certified reference materials and regular verification of instrument performance. The method also allows for the use of alternative detection limits, such as those specified in ISO 17025, to accommodate different analytical requirements.
Understanding the significance of indium in water samples is essential for industries involved in metal extraction, electronics manufacturing, and wastewater treatment. By adhering to ASTM D5673, laboratories can ensure accurate and reliable results that are comparable with other testing facilities worldwide.
