  • Method of stablizing and solidifying elemental mercury using sulfur and paraffin
    Patent number: 8119087
    Abstract: Provided is a method of stabilizing and solidifying elemental mercury using sulfur and paraffin. The method includes reacting elemental mercury with sulfur to prepare a mercury sulfide compound, adding a mixture of the mercury sulfide compound and the remaining sulfur after the reaction to high-temperature liquid paraffin to melt the remaining sulfur, and cooling the sulfur to solidify the mercury sulfide compound. According to the method of stabilizing and solidifying elemental mercury using sulfur and paraffin, a surface of a solidified product is covered with a thin paraffin layer to prevent exposure to the outside.
