GB/T 15264-1994 《Ambient air--Determination of lead--Flame atomic absorption spectrophotometric method》 Related products

The GB/T 15264-1994 standard specifies a method for the determination of particulate lead in environment air using flame Atomic absirption spectroscopy-tometry, AAS. The method is simple, fast and accurate, and is suitable for the detection of particulate lead in environment air. The detection limit of the method is 0.5 μg/mL, and the minimum detection concentration is 5 × 10 ^ -6 mg/m ³. After collecting the sample through a fiberglass filter membrane, it is leached with nitric acid and hydrogen peroxide, and then the flame atomic absorption measurement is carried out to ensure the accurate detection of lead in the air. This standard provides effective technical support for environment air mass monitoring.
