摘要: A method for the determination of chromium in sea water is described which requires minimal sample preparation. The from filtered samples oxidized with permanganate, extracted ammonium pyrrolidine dithiocarbamate into MIBK, and analyzed by atomic absorption spectrometry a fuel-rich air-acetylene flame. Non-filterable solids are 12 M hydrochloric acid analyzed. Detection limits methods 0.05 μg 1-1 soluble phase 0.06 particulate phase.
