A rapid method for determining tin and molybdenum in geological samples by flame atomic-absorption spectroscopy
January 1, 1985
The proposed method uses a lithium metaborate fusion, dissolution of the fusion bead in 15% vv hydrochloric acid, extraction into a 4% solution of trioctylphosphine oxide in methyl isobutyl ketone, and aspiration into a nitrous oxide-acetylene flame. The limits of detection for tin and molybdenum are 1.0 and 0.5 ppm, respectively. Approximately 50 samples can be analysed per day.
