Electrochemical modification is to change the electrical and chemical properties of activated carbon surface by using micro electric field, so as to improve the adsorption selectivity and performance.It does not need to add chemical agents, does not need to heat, does not cause pollution to the environment, low energy consumption, only a few hundred millivolts, easy to operate.The results show that the adsorption equilibrium of activated carbon is dependent on the electric potential: the adsorption amount of activated carbon increases with the increase of the potential, and the adsorption speed is accelerated;Arpolarity polarization is beneficial to the adsorption of chloroform by activated carbon, while cathodic polarization inhibits the adsorption of chloroform by activated carbon 3-341]. Activated carbon heteroatom carrier and compound modificationActivated carbon has very high stability and good activity, these two basic properties become the activated carbon as a catalyst or catalyst carrier conditions.By introducing certain heteroatoms and compounds on the surface of activated carbon by liquid phase deposition, the adsorption performance of activated carbon can be increased by using the binding effect between these substances and adsorbents.compounds, which has the advantages of increasing the reaction rate and increasing the adsorption capacity.Yang Quanhong et al. 'Using FESO;Activated carbon material was modified. activated charcoal pellets bulk 

Firstly, the adsorption and desorption isotherms of three activated carbons for coconut shell-based smoke and three activated carbons for apricot kernel based smoke were determined by low temperature nitrogen adsorption method. The specific surface area and total pore volume were calculated by BET model. The microstructure parameters and pore size distribution of micropores and mesopores were calculated by H-K method and BJH method, respectively. The surface morphology of activated carbon was also observed by scanning electron microscope. The results show that the pore structure of activated carbon for commercial tobacco is different at present. Among the six activated carbon samples selected, Y1 and CTN are microporous activated carbon, and the micropore ratio is more than 97%. X3 and X5 samples were medium pore activated carbon with microporosity of only 69.3% and 55.5%. The micropore contents of X2 and Y5 samples were 87.2% and 81.8%, respectively, between X3 and X5 samples and Y1 and CTN samples. SEM observation of the surface morphology of activated carbon samples for smoke showed that the surface of activated carbon was honeycomb-like with developed pores, and the large pores were all in the shape of open pipe structure. There were various small circular and elliptical holes on the pipe wall. www.wyactivatedcarbon.com
