08.05.2009An analytical method for simple and rapid determination of methylmercury in sediment and organism samples is described. The proposed method employs the oxygen combustion-gold amalgamation using Direct Mercury Analyser (DMA-80) after complete removal of MeHg by organic extraction and back extraction to an aqueous medium.

Mercury forms amalgams most easily with metals like gold, silver and aluminum. Mercury does not react with all metals; it will not form an alloy with iron, for example, and it is reluctant to form amalgams with most transition metals, excluding manganese, copper and zinc.

Does gold float in mercury? Provided that gold sinks into mercury, This means that the mercury level is about $13$ times higher than that of water. Some artefacts, including pieces of lead, silver and steel, that sink in water will therefore float on mercury. Parts of gold sink, though because gold has a greater density than mercury does.
