Jan 01, 1980INTRODUCTION For the routine determination of mercury in marine environment, especially in sea water where natural levels would not exceed 10 ng I"1, investigation to increase the sensitivity of conventional method is needed yet. Usually, analysis of mercury are conducted by cold-vapor and atomic absorption procedure (Hatch and Ott, 1968).Measuring principle UV-AbsorptionWavelength 254 nmUV detectors Silicon, UV-enhanced, temperature controlledMercury, atomic absorption spectrometric, flameless2.1 The cold-vapor, flameless, atomic absorption procedure is based on the absorption of radiation at 253.7 nm by mercury vapor. Organic mercury compounds, if present, are decomposed by hot (95°C) digestion with potassium permanganate and potassium persulfate in acid solution. The mercuric ions are then reduced to the elemental state with stannous chloride, and the mercury vapor isMercury (Hg) Analyzer - Buck Scientific410 Cold Vapor Mercury Analyzer. Spares.
