What is Application of Inductively Coupled Plasma Sector Field Mass Spectrometry for Low-level Environmental Americium-241 Analysis about?
An improved and novel sample preparation method for 241 Am analysis by inductively coupled plasma sector field mass spectrometry has been developed. The procedure involves a selective CaF 2 pre-concentration followed by an extraction chromatographic separation using TRU TM resin. The achieved absolute detection limit of 0.86 fg (0.11 mBq) is comparable to that of alpha spectrometry (0.1 mBq) and suitable for low-level environmental measurements. Analysis of different kinds of environmental standard reference materials (IAEA-384 -Fangataufa lagoon sediment, IAEA-385 -Irish Sea sediment and IAEA-308 -Mixed seaweed from the Mediterranean Sea) and alpha spectrometry were used to validate the procedure. The chemical recovery of sample preparation ranged between 72 and 94%. The results obtained are in good agreement with reference values and those measured by alpha spectrometry. The proposed method offers a rapid and less labor-intensive possibility for environmental 241 Am analysis than the conventionally applied radioanalytical techniques.
