Activated carbon adsorbate molecules transferred to the carbon clearance gravity body can be divided into the following steps: 1, the external diffusion: adsorption from solution dispersed mass transfer to the adsorbent surface apricot shell activated carbon price, to be surrounded by activated carbon adsorption membrane processes, and adsorbate molecules transferred to the vicinity of the adsorbent surface. 2, the surface diffusion: the adsorbate is adsorbed along the outer surface of the activated carbon diffuses into the pores inside the process 3, the internal particle diffusion: adsorbate is transferred to the position of the activated carbon adsorption holes inside the process. 4, physical adsorption: After contact with the activated carbon adsorption quality, adsorbate molecules attached to the suction position, the loss of freedom, then the adsorbate concentration will reduce exports and changes in the concentration in the case of exports, to represent its adsorption rate. 5, desorption: adsorbate from the active position out to regain freedom, from the interior of pores of the activated carbon removal process, steps 4 and 5 when the reaction rate considerably, then the activated carbon adsorption quality of homeostasis. 6, chemisorption: adsorbate and the adsorbent surface chemical reaction apricot shell activated carbon manufacturers, depending on the nature of the substance and activated carbon adsorption vary. 7, the surface renewal: is adsorbed on the activated carbon adsorption, chemical reaction product is highly volatile, fire and metal ion catalyzed hydrolysis, and therefore the removal of apricot shell activated carbon iodine adsorption from the activated carbon, activated carbon adsorption recovery , and can be used again. Typically external diffusion, surface diffusion and diffusion rate of diffusion within the particles determines the rate of activated carbon adsorption, however, the flow in the liquid phase adsorption system, if the flow rate is too slow, too slow will cause convection, the internal particle diffusion rate of a liquid phase adsorption The control factor. Test Method for liquid coconut coconut shell activated carbon adsorption capacity, is the preparation of a certain concentration of chemisorption solution. With an amount of coconut shell activated carbon sample sufficiently adsorbed, and then measuring the concentration of the solution after adsorption. Differences adsorbate concentration before and after the coconut coconut shell activated carbon adsorption capacity can be calculated coconut shell activated carbon adsorption of certain substances in solution. Often water capacity, methylene blue adsorption, iodine adsorption, phenol adsorption, caramel and other indicators characterize the liquid coconut shell activated carbon adsorption capacity. Tetrachloride adsorption - this is the characterization of coconut shell activated carbon adsorption capacity for gas indicators. Activated carbon at a certain temperature, the air is saturated with carbon tetrachloride by placing a U-shaped tube or straight pipe coconut shell activated carbon layer of a certain thickness, when reached saturation adsorption coconut shell activated carbon adsorption specimen tetrachloride King and the sample mass ratio quality carbon, carbon tetrachloride adsorption rate is pq coconut shell activated carbon. Coconut shell activated carbon which mainly contains high amounts of material made of carbon such as wood, coal, shell, bone, petroleum residue and so on. The coconut shell is the most commonly used raw material, under the same conditions, the activity of quality coconut shell activity and other special features are the best, because there is the largest surface area. Generally coconut shell activated carbon surface area (BET) greater, the greater the suction force, but sometimes not necessarily. BET adsorption method is to use nitrogen or butane application parameters measured total surface area of ??coconut shell activated carbon. Logically, the greater the BET adsorption force is greater. But in practice this concept has its limitations, because coconut shell activated carbon has a big hole hole, the difference between the holes and pores, sometimes only a hole portion size fits into a particular type of adsorbent. In gas phase applications, small molecules are adsorbed into the micropores. Then the concept of the total surface area is used in combination. As for the coconut shell activated carbon adsorption of the metal complex, involving the formation of chemical bonds nor BET bigger the better.
