title: Atomic absorption spectroscopic determination of molybdenum in plant tissue and blood plasma.
abstract: A method is presented for determining molybdenum in plant tissue and blood plasma by flame and flameless atomic absorption spectroscopy (AAS). The samples are digested with HNO3-HCIO4, and the metal is separated by chelation, extracted into methyl isobutyl ketone, and analyzed by AAS. Recoveries of molybdenum from fortified samples ranged from 92.0 to 98.9%. The limits of detection on the flame and graphite furnace were 10 and 2 ng/mL, respectively.
