Abstract

Selenium concentrations in marine sediments were determined by gas chromatography with electron capture detection. The sediments were dissolved in an acid mixture. Selenium was converted into 5-nitroplazselenol, extracted into toluene, and introduced into the chromatograph. The detection limit was 0. 2 pg of Se injected or 30 ng of Se/g of sediment. The standard deviation was about 7%.
