Direct determination of low arsenic concentrations in oil products by GFAAS technique
INTRODUCTION
Light petroleum fractions containing C4-C15 hydrocarbon compounds are used as a feedstock for petrochemical processes that can be severely affected by trace amounts of arsenic. A simple graphite furnace atomic absorption spectroscopy (GFAAS) procedure for arsenic determination at ppb levels in naphtha, gasoline, gas condensate, and similar products is proposed.
