 Activated carbon than the surface area of ??research is very important, the test data of the activated carbon surface area only by adopting the results of the BET method is a true and reliable, the current instrument can only do a direct comparison method detection now also be eliminated . At home and abroad BET unified multi-point BET method, at home and abroad to develop the specific surface area measured by the standard are based on the BET test method, see our national standards (GB / T 19587-2004) - gas adsorption BET principle Determination of the surface area of ??solid material. In fact, than the surface area of ??detection is time consuming, due to the different adsorption capacity of the sample, some samples of the test may need to spend a whole day, if the testing process is not fully automated, that testers can not leave on time, and to highly concentrated, and observe the instrument panel, control knobs, too easy to cause the failure of the testing process, which will waste valuable time testers. F-Sorb 2400 surface area analyzer is truly able to achieve the BET method of detection equipment (both the direct comparison method), more importantly, the F-Sorb 2400 surface area analyzer is so far the only fully automated intelligent than the surface area of ??detection equipment, test results, and international consistency is high, stability is also very good, while reducing human error and improve the accuracy of test results. 



 Nutshell activated carbon in wastewater treatment as a result of the activated carbon water pretreatment requirements, and the activated carbon is expensive, wastewater treatment, activated carbon is mainly used to remove trace contaminants in the wastewater, in order to achieve the purpose of deep purification . 

 41 activated carbon treatment wastewater containing chromium. Chromium is a larger amount of a metal material plating, hexavalent chromium in the waste water with different pH value, respectively, exist in different forms. Activated carbon has a highly developed porous structure and high specific surface area, with a strong physical adsorption capacity of Cr (VI) in wastewater can be effectively adsorbed on the surface of activated carbon in a large number of oxygen-containing groups such as hydroxyl (-OH ), carboxyl (-COOH), they have electrostatic adsorption function, the chemical adsorption of Cr (VI). Can be used for treatment of electroplating wastewater containing Cr (VI) adsorption after waste water can reach the national emission standards. The experiments show that: the solution of Cr (VI) concentration was 50 mg / L, pH = 3, the adsorption time 1.5h, activated carbon adsorption and Cr (VI) removal efficiency to achieve the best results. Therefore, the use of activated carbon treatment process of wastewater containing chromium is the result of the combined effects of activated carbon physical adsorption, chemisorption, chemical reduction of Cr (VI) solution. Activated carbon treatment wastewater containing chromium adsorption and stable performance, high efficiency, low operating costs, there are certain social and economic benefits. 

 52 activated carbon treatment of wastewater containing cyanide. In industrial production, the wet extraction of gold and silver, chemical fiber production, coke, ammonia, electroplating, gas production industry the use of cyanide or byproduct cyanide, and thus in the production process is bound to emit a certain amount of cyanide wastewater. Activated carbon for the purification of waste water has a rather long history, more and more used in processing wastewater containing cyanide reported in the literature but As CN_, of HCN on the activated carbon adsorption capacity is generally 3mgCN/gAC ~ 8mgCN/gAC due The different varieties, on the cost of processing uneconomical. 

 63 activated carbon treatment of mercury-containing wastewater. Activated carbon adsorption of mercury and mercury-containing compounds of the performance, but the adsorption capacity is limited, only suitable for dealing with low mercury content of wastewater. If a higher concentration of mercury, and can use chemical precipitation treatment, mercury after processing about 1mg / L, up to 2-3mg / L, then the activated carbon for further processing. 

 74 Activated Carbon Treatment of Phenolic Wastewater. Phenolic Wastewater widely from petrochemical plants, resin plants, coking plants and refining plants. The experiment proved that: the performance of activated carbon adsorption of phenol, the temperature is not conducive to adsorption, the adsorption capacity decreases; increasing the temperature to reach adsorption equilibrium time. There exists an optimum value for the amount of activated carbon and adsorption time, in acidic and neutral conditions, the removal rate changes; strong alkaline conditions, phenol removal was a sharp decline, the stronger the alkali, the worse the adsorption effect. 









 Nutshell Activated Carbon Appearance: black granular 
 Nutshell Activated Carbon selected shell quality apricot, peach shell, walnut shell, dates shell, fruit shell as raw materials, activated carbon with carbonization, activation, over the superheated vapor Cui and other refining process, the appearance of the black amorphous particles produced by the series of processing from an activated carbon.
