ASTM D6647 Acid Soluble Iron Atomic Absorption FAQs
ASTM D6647 is a laboratory test method used to determine the concentration of acid-soluble iron in samples using atomic absorption spectroscopy.
Iron concentration measurement helps identify contamination, corrosion products, and water quality issues in environmental and industrial systems.
Acid digestion dissolves iron in the sample, converting it into a soluble form suitable for accurate instrumental measurement.
Factors include sample preparation, calibration accuracy, instrument stability, and potential interference from other elements.
Yes, atomic absorption spectroscopy is capable of detecting very low concentrations of iron in samples.
ASTM D6647 determines the acid-soluble iron content in granular and powdered activated carbon. The test involves grinding and drying a representative sample, then treating it with dilute hydrochloric acid to extract soluble iron. The solution is boiled, cooled, and filtered before the iron concentration is measured using atomic absorption spectroscopy (AAS). The results are used to determine the acid-soluble iron content, helping evaluate activated carbon quality and its suitability for applications such as water purification, chemical processing, and decolorization.
