Description
Technical field
It is synthetically prepared technical field the present invention relates to removal of mercury material, is removed it is more particularly related to which one kind is novel
The synthesis preparation method of mercury material.
Background technique
Mercury pollution refers to the environmental pollution as caused by mercury or compound containing mercury, and the source of mercury pollution is broadly divided into nature
Source and artificial source, it is to be discharged in the form of elemental mercury from vapor to atmosphere that artificial source, which has 80%, mostlys come from fuel combustion
The approach such as burning, mining, smelting, waste incineration, in addition have 15% to enter soil by approach such as fertilising, pesticide, domestic refuses,
Water body is entered in the form of industrial wastewater there are also 5%, mercury is one of strongest heavy metal element of environment Poisoning, various mercuration
The toxicity difference for closing object is very big, and the mercuric chloride in inorganic mercury is extremely toxic substance, and the phenyl mercury in organic mercury decomposes comparatively fast, and toxicity is not
Greatly, and methyl mercury enters human body and is easier to be absorbed by, it is not degradable, drain it is very slow, especially be easy accumulate in brain, toxicity is most
Greatly, the purposes of mercury and mercuric compounds is very extensive, and it is a variety of to be mainly used for chemical industry, metallurgy, electronics, light industry, medicine, medical instrument etc.
Industry, in total dosage of mercury, mercury metal accounts for 30%, and the mercury of compound state accounts for about 70%, and mercury can be used as perhaps polymetallic molten
Agent generates amalgam, and metallurgical industry often extracts the metals such as gold, silver and thallium with amalgam process, and chemical industry mercury makees cathode to be electrolysed food
Salting liquid produces caustic soda and oxygen.
Active carbon can be used to be adsorbed for mercury in industrial product, and active carbon is a kind of porous solid carbonaceous of black, by
For coal by crushing, forming or carbonized with uniform coal grain, activate production, main component is carbon, has very strong absorption property,
For a kind of extremely wide industrial adsorbents of purposes, but in the prior art in flue gas demercuration and the sewage removal of mercury, the suction of active carbon
Attached efficiency is lower, and then is easy to cause removal efficiency of mercury poor.
Summary of the invention
In order to overcome the drawbacks described above of the prior art, the embodiment of the present invention provides a kind of synthesis system of novel removal of mercury material
