In order to verify the accuracy of the simulation calculation, two 12g activated carbon bags thickness of activated carbon ~ 1.5cm) were put into the container containing uranium ore, and then taken out after radon adsorption for 30 min and 85 min. After continuous measurement, the change curve of total Y number of activated carbon over time could be obtained.
According to the adsorption duration used in the experiment and the appropriate value of n (in the calculation process, when the adsorption duration is 30 min, n=480
When the adsorption time is 85 min, take n-600), and the calculated theoretical curve is shown in FigureIt can be seen from the figure that the measured curve is in good agreement with the theoretical curve.Fig. 2 is the simulation result of the total number of Y taken out over time after activated carbon adsorbs 1 radon atom from the environment every second and continues to adsorb for 3 days.After the activated carbon was taken out, the total number of V reached the maximum after t time, and then the total number became smaller. After about 50 min, the total number of V decreased by a negative exponential function.activated carbon manufacturer in Germany
The curve can be divided into a stationary area and a measuring area. The width of the stationary area (i.e. the duration of the stationary area) is set at (t+50) min, followed by the measuring area.Activated carbon, is black powder or block, granular, honeycomb amorphous carbon, but also a regular arrangement of crystalline carbon.In addition to carbon elements, activated carbon also contains two kinds of admixtures: one is the chemical combination of elements, mainly oxygen and hydrogen, these elements are due to incomplete carbonization and residual in the carbon, or in the activation process, foreign non-carbon elements and activated carbon surface chemical combination;Another kind of admixture is ash, which is the inorganic part of activated carbon, and ash in active carbon is easy to cause secondary pollution.Because of its strong adsorption, activated carbon is widely used in production,In the life.Activated carbon material is processed by the amorphous carbon, has a large specific surface area, the gas, solution of inorganic or organic matter and colloidal particles have good adsorption capacity.Activated Carbon materials mainly include Activated Carbon (AC) and Activated Carbon Fibers (ACF), etc.Activated carbon material as a kind of excellent adsorbent, mainly because of its unique adsorption surface structure and surface chemical properties.Activated carbon material has stable chemical properties and high mechanical strength.
There is no obvious rule of counting in the standing zone. Should be avoided during this period of time.Total number of;The measurement area is countedgas phase adsorption of activated carbon.
Can be used for exhaust treatment, air purification, solvent recovery, gas separation, deodorization, desulfurization and denitration, industry.Raw material gas refining, gas chromatography filler, air sampler, fresh-keeping, ozone removal, cigarette filter nozzle, gas adsorption storage, military and civil gas masks, etc.(2) liquid phase adsorption of activated carbon.Tap water treatment, pure water manufacturing, industrial and domestic sewage advanced treatment, decolorization refining, blood purification, gold recovery, double capacitor electrode, pharmaceutical carbon, etc.(3) catalyst (catalyst) with activated carbon.wholesale activated carbon pellets

Both can be directly used as a catalyst for this industrial process (such as phosgene synthesis, synthesis of vinyl acetate, etc.), more time activated carbon is used as a catalyst carrier (such as carrying precious metal pins, men, palladium, nails, gold made of pin carbon, palladium carbon catalyst, etc.).(1) solvent recovery.Such as recycling printing industry with xylene, toluene, benzene and other solvents;Recycling organic solvents such as ethanol, acetone, ester and ether from plastics and artificial leather industry;Recycling of hexanone in tape factory;Recycling of dichloromethane from resin processing plants, etc.(2) air purification.Such as electronic, pharmaceutical industry aseptic workshop air purification;Removal of ozone in the air of the copy room and computer room;The removal of foreign odor in the air of confined space;Odor removal from refrigerators, etc.(3) Nuclear and biochemical protection.Nuclear radiation, biological warfare agents, chemical warfare agents are weapons of mass destruction, activated carbon is loaded with a variety of chemical agents can effectively protect it
Activated carbon or chemical-loaded activated carbon is often used as a key component of personal protective equipment in the presence of toxic gases in the civilian industry. During the SARS crisis in late 2002 and early 2003, special protective masks with activated carbon loaded with silver played a role in protecting health care workers.
(4) deep purification treatment of tap water.Practice has proved that activated carbon is still has the best effect of the depth of water purification products, its dosage in recent | years show how multiple growth.
