[Determination of total amounts of mercury in unfrothing preparations].

Mercury and its organic (CH3 HgCl) and inorganic (HgCl2) compounds are very poisonous. The analytical control of trace amounts of metals in products that are used in the food industry is of great importance. In this work, the determination of mercury, present at trace levels in industrial unfrothing preparations. Mercury was determined by the cold-vapour atomic absorption spectrometry. The method allows for accurate determination of mercury and as little as 0.01 mg ph Hg per kilogram of product can be determined.
