Abstract
Inorganic tin and organotin compounds in artificial sea water were determined at sub-p.p.b. levels. These compounds are separated from matrix elements in aqueous solutions by benzene extraction of their iodide forms from a 2M sulphuric acid-1.5M sodium iodide solution containing 1 percent m/V ascorbic acid. The organic phase was partially vaporized to pre-concentrate the analytes and was injected directly into the treated graphite tube; the signal was measured by a Zeeman atomic absorption spectrometer. Using a matrix modifier, inorganic tin could be directly determined at sub-p.p.m. levels in the presence of organotin compounds.
