| Introduction | Mercury is a metal element, commonly known as Mercury, English name Mercury, chemical element symbol Hg, atomic number 80, group IIB metal of the periodic table, melting point -38.87 °c, boiling point 356.6 °c, density 13.59g/cm3. Mercury is a bright silver-white heavy liquid, and is also the only metal in liquid form at normal temperature and pressure. At room temperature, Mercury chemical stability, mercury vapor and mercury compounds are highly toxic (chronic). Mercury can dissolve many metals (such as gold, silver, etc.), the formation of amalgam (also called amalgam). |
| History of discovery | the presence of mercury was found in the ancient Egyptian graves in the 1500-year period before the birth season. In ancient China, Mercury was thought to prolong life, treat fractures and maintain health, although it is now known to cause serious health damage. According to historical records, Mercury is used as water in Qin Shihuang's mausoleums and flows in a model of the land under his rule. Qin Shihuang died of a mixture of Mercury and jade powder prepared by alchemists, which led to liver failure, mercury poisoning and brain damage, which were originally intended to immortalize Qin Shihuang. Ancient Chinese women also used a small amount of oral Mercury for contraception. The ancient Greek used mercury in ointment, the ancient Egyptian and ancient Roman to add it to cosmetics, but sometimes such cosmetics can cause deformation of the face. A pool of mercury was found beneath a mark on a Central American field in the great city of lamané of the Maya civilization. About 500 years ago, Mercury has been used to make alloys with other metals. In the 18th and 19th centuries, Mercury was used to remove hair from the skin of felt animals, which caused brain damage in many hat workers. Mercury was also used to treat syphilis before the advent of penicillin. |
| Source | Mercury is a relatively rare element in the Earth's crust, containing only 0.08ppm. Because of the chemical nature of Mercury, it is not easy to ore with the major elements of the Earth's crust, so taking into account the content of mercury in ordinary rocks, Mercury in Mercury is very rich. The highest grade mercury ore has 2.5% of the quality of Mercury, even if the lowest grade is 0.1%, is 12000 times the content of the Earth's crust. Mercury is rare in the metal element, common in cinnabar, chlorine sulfur mercury ore, sulfur mercury antimony ore and other minerals, which is the most common in cinnabar. Mercury mines are generally formed in the very new orogenic belt, where high-density rocks are pushed to the crust. Mercury mines are common in hot springs and other volcanic areas. |
| Applications | The most commonly used applications of mercury are in the manufacture of industrial chemicals and in electronic or electrical products. Mercury is also used in thermometers, especially those measuring high temperatures. More and more gaseous mercury is still used in the manufacture of fluorescent lamps. In addition to the use of mercury: gold can be decomposed from its minerals, so it is often used for gold ore. History has been used for the treatment of syphilis and other sexually transmitted diseases, but because of excessive side effects and has been eliminated. Other uses: mercury switches, pesticides, as Mercury cathodes in the production of chlorine and sodium hydroxide, preservatives, as electrodes, batteries and catalysts in some electrolysis equipment. |
| preparation method | preparation method of Mercury: 1. The cinnabar is heated in flowing air, and mercury vapor is obtained by reduction, and the vapor is condensed and collected to obtain mercury metal. The cinnabar ore is crushed and enriched by flotation, and then calcined in air or heated with quicklime to distill Mercury. This method is commonly used in the industry. |
| toxicity | pure mercury is toxic, most of its compounds and salts are very toxic, oral, inhalation or exposure can lead to brain and liver damage, so most thermometers today use alcohol instead of mercury, but because of its high accuracy, some medical thermometers still use mercury. In the standard gas temperature and pressure, the biggest danger of pure mercury is that it is easy to oxidize and produce oxidized mercury, and oxidized mercury is easy to form small particles to increase its surface area. Although pure mercury is less toxic than its compounds, it is still a very dangerous pollutant because it forms organic compounds in the organism. The most dangerous organic compound of mercury is dimethylmercury [(CH3)2Hg], which can be lethal with only a few microliters of exposure to the skin. Mercuric sulfide is a less toxic compound. |
| Use | used in the manufacture of mercury salts and amalgam and in organic synthesis, and also used as reducing agent |
| production method | 1. The platinum wire is inserted into the FIG to be purified as an anode, and the other platinum sheet is inserted into a 15% (mass) dilute nitric acid electrolytic solution (without touching the bottom Mercury) as a cathode, the ratio of purified mercury to dilute nitric acid was 10kg: 1000mL, the electrolysis voltage was 2-3v, and the current was 3-4A. After the initiation of the electrolysis, the electrolyte was continuously stirred and a new electrolyte was reintroduced. The electrolysis was continued until the color of the electrolyte did not become darker. The acid solution should be washed with water until the small acid content is acceptable. Add equal volume of Mercury and water to the pumping bottle, the mercury is removed by introducing air into the Mercury by means of vacuum extraction and pumping with water until the upper layer water is no longer turbid. Discard the upper layer of water, MErcury Surface with filter paper, that is, purified mercury. Figure XII-1 air oxidation device figure XII-2 Mercury scrubbing device figure XII-3? If the mercury distillation unit is to produce high-purity Mercury, the extracted mercury should be washed with 5% reagent nitric acid and pure water in the washing column (the Mercury surface must be clean), after filtering with four layers of fine gauze, the surface was dried by suction with filter paper, vacuum distillation was carried out, the degree of vacuum was 4665-6665PA, and the 120-140 ° C. Fraction was collected to obtain high purity Mercury. At present, the industrial production of mercury is mainly based on the fire method, and the wet method is the secondary method. The fire method is simple and the production cost is low. The mercury ore is calcined in an oxidizing atmosphere at a temperature of 650 to 750 ° C. To decompose it into sulfur dioxide and metallic mercury. The mercury vapor escapes from the furnace gas and condenses into a liquid state in the condensation system to obtain "gross Mercury" with a grade of about 99 μ5%, which is filtered through deer skin and canvas, can be used as a general industrial use of mercury. Mercury Hydrometallurgy is mainly used for the treatment of mercuric sulfide concentrates. HgS is leached from the ore with a 25% aqueous mixture of sodium sulfide and caustic soda, and then the solution is electrolyzed with a diaphragm, with graphite as the anode and Mercury as the cathode, the purity of Mercury obtained by electrolysis can reach more than 99.99%. Commercially available Mercury often contains impurities. If pure mercury is required, it can be further purified in the laboratory by the following method. Purification method 1. The main impurities mixed into the commercially available mercury are water, oil, grease, etc., and the impurities dissolved in Mercury are zinc, copper, lead, tin, etc. The mixed solid impurities can be removed by filtration with fine pore filter paper or leather, and the dissolved metal impurities can be removed by filtration by passing air through the device shown in Fig, hg2 (NO3)2 solution (15% ~ 20% nitric acid, 5% mercurous nitrate) was used for further purification in the device shown in Fig, A more pure mercury product is available. Purification method 2. Although the mercury obtained by The purification method 1 has a very high purity, gold, silver and a material forming an amalgam mixed in the Mercury cannot be removed by purification by the purification method 1. When a relatively small amount of pure mercury is required, the Mercury obtained by The purification method 1 can be obtained by further distillation in the apparatus shown in the figure. |
