DISPOSAL OF ELEMENTAL MERCURY VIA SULPHUR REACTION

mercury-containing by means of the use of polymeric sulphur compounds. 2. EXPERIMENTAL 2.1 Materials and methods The reaction between elemental Hg elemental and S in non stoichiometry conditions was carried out by means of the mechanical energy provided by a planetary ball mill (FRISTSCH mod. Pulverisette) containing four stainless steel balls.

Formation of metacinnabar by milling of liquid mercury and ...

Sep 15, 2010  With the application of mechanical energy provided by a ball mill to a mixture of liquid mercury and elemental sulfur it is possible to obtain mercuric sulfide in the form of black metacinnabar powder. Excess sulfur above the stoichiometric value favors the reaction efficiency and lowers the temperature inside the milling jar.

Sep 15, 2010  The reaction mechanism was monitored with a scanning electron microscope. The impact and friction forces of milling on the Hg and S mixture resulted in the formation of metacinnabar by reducing the size of mercury drops, giving rise to microspheres, and lowering the surface tension to allow sulfur grains to become adhered at the reaction interface.

Jul 15, 2014  The formation of intermediates was significantly influenced by the diameter of the ball. In order to show this trend quantitatively, we measured the recovery ratio defined as the proportion of powder that was recovered from the mill pot after the reaction, to the amount of metal mercury and powdered sulfur in the mill pot before the reaction.

Amalgam (chemistry) - Wikipedia

Important amalgams Zinc amalgam. Zinc amalgam finds use in organic synthesis (e.g., for the Clemmensen reduction). It is the reducing agent in the Jones reductor, used in analytical chemistry.Formerly the zinc plates of dry batteries were amalgamated with a small amount of mercury to prevent deterioration in storage. It is a binary solution (liquid-solid) of mercury and zinc.
