Technical field
The present invention relates to a kind of preparation method of native sorbing material, particularly relate to a kind of preparation method of modified attapulgite clay sorbing material.
Background technology
Carbon dioxide is to be similar to one of major pollutants in the airtight or smooth place that ventilates of the underground space, and its source mainly contains two aspects, the one, and the gas of breathing out and producing from human body, the 2nd, from the burning of fuel.Because underground space difficulty sees sunlight, and lack directly the facility that can ventilate with the external world, thereby the Design of ventilation of the underground space and crowd activity there is direct influence to air quality, the especially gas concentration lwevel of these underground spaces.Carbon dioxide is the essential material of Human Physiology, belongs to the excitant of respiratory center, and therefore, indoor carbon dioxide is used as the parameter of ventilation condition, generally human body is not produced toxic action.When concentration surpassed certain limit, then it was to the toxic effect of human body.High concentration carbon dioxide (＞15000ppm) can cause central nervous system to poison, make that respiratory center is excited earlier, the back suppresses, cause paralysis at last and suffocate, body anoxic and cause substantial viscera hyperemia, oedema such as lung, kidney.Therefore, preparation is a kind of has the material that adsorbing carbon dioxide efficiently purifies air and has bigger realistic meaning.Document discloses a kind of siliceous nano calcium oxide high temperature carbon dioxide adsorbent, by nano-calcium carbonate (CaCO
3) usefulness sol-gel process coated silica (SiO
2) or nano calcium carbonate is direct and the nano-silica powder end evenly is mixed and made into siliceous nano-calcium carbonate calcium powder, again with the forming agent mixed-forming, forms at 600～800 ℃ of temperature lower calcinations, under hot conditions carbon dioxide is had adsorption effect preferably.Document discloses a kind of material that utilizes organic amine to impregnated in the absorbing carbon dioxide on the active carbon, and the hygrometric state product can reach 127.0mg/g to the adsorbance of carbon dioxide.Document discloses a kind of method of utilizing the carbon dioxide absorber of calcium oxide and the extensive preparation of rice husk, and this adsorbent can repeatedly circulate and keep good CO in the calcination/carbonation course of reaction
2The seizure performance.Document discloses a kind of raising zeolite adsorption CO
2The method of capacity is to utilize sodium carbonate, NaOH or sodium calcium salt to mix weak solution the 13X zeolite is handled to reach the purpose to the efficient absorption of carbon dioxide.
Concave-convex clay rod is a kind of natural minerals, have high-specific surface area, characteristics such as the ion exchangeable ability is strong, chemical stability good, strong absorptive, be widely used as in fields such as petrochemical industry, daily-use chemical industry, fine chemistry industry, food processing, using for adsorbent, catalyst carrier and antiseptic carrier.And the Concave-convex clay rod of modification be yet there are no report as the material of adsorption cleaning carbon dioxide.
