Embodiment Construction

[0027] The method invention will be further described in detail in combination with examples, but the embodiment of the invention is not limited thereto. Screen fine zinc or silver or gold particles or chips as materials for liquid mercury treatment. If there are no small particles or chips, it is best to process large particles into small particles. The larger the contact area between reactants and liquid mercury, the faster and more complete the reaction. The use of fine granules or chips allows for the fastest processing of liquid mercury with the greatest savings in material. Zinc dust should not be used due to its explosive nature.

[0028] Then put the reactant into citric acid to treat the oxide film and impurities on its surface. It should be noted that the zinc treatment should not exceed 2 minutes to prevent it from excessively reacting with acid and causing waste.

[0029] Remove the treated particles or debris from the citric acid and sprinkle the excess particl...

Abstract

The invention relates to the field of liquid mercury treatment, particularly the treatment field of liquid mercury leakage in laboratories or households and the treatment field of waste liquid mercuryinside factories. Various disadvantages such as treatment incompletion, secondary leakage, used material risk and toxic substance generation exist in existing liquid mercury treatment manners. The method is used for solving the problem that an existing liquid mercury treatment method is low in practicability and high in risk factor, the characteristic that an amalgam reaction can occur between mercury and partial metal is proposed and used, the non-poisonous and safe metal is used for reacting with liquid mercury in normal temperature conditions, so that the liquid mercury is converted into anon-poisonous and safe solid substance. The innocent treatment of mercury is realized, and simultaneously, the solid substance is also more convenient to store.

Description

[0001] 2. The technical field of the present invention [0002] The invention relates to the field of liquid mercury treatment, in particular to the field of treatment of liquid mercury leakage in laboratories or households and the field of treatment of a large amount of waste liquid mercury in factories. 3. Background technology [0003] Liquid mercury, commonly known as mercury, is widely used in many fields. It can be used in the manufacture of industrial chemicals, electronic and electrical products, and thermometers (especially high-temperature thermometers), as well as in various experiments (such as high-pressure mercury intrusion experiments). Mercury is liquid at room temperature. It is a silver-white shiny heavy liquid with stable chemical properties. It is insoluble in acid and alkali and belongs to highly toxic (chronic) chemicals. Ingestion of trace amounts of liquid mercury is generally non-toxic, but mercury vapor and mercury salts are highly toxic and can cause...
