 The pore structure of activated carbon mainly includes specific surface area, pore volume and pore size distribution, which are key parameters affecting the adsorption performance of activated carbon and important factors affecting dioxin adsorption. The adsorption of dioxin on activated carbon is essentially a pore filling process. After the dioxin molecules contact the surface of activated carbon through external diffusion, they diffuse into the pores through the pore channels on the surface of activated carbon. Today we will explain its influence in detail. 

 Factors affecting the adsorption of dioxin by activated carbon 

 Pore size distribution: The pore size of activated carbon needs to match the size of dioxin molecules for effective adsorption. The suitable pore size range is 2.0~5.0nm. 

 Specific surface area: The larger the specific surface area, the stronger the adsorption capacity. Generally, the specific surface area is required to be greater than 500m²/g. 

 Pore volume: Pore volume and pore volume are also important factors affecting the adsorption effect, and the specific pore volume is usually required to be greater than 0.2cm³/g. 

 Effects in practical applications 

 In practical applications, activated carbon achieves effective adsorption and elimination of dioxins through its unique pore structure and physical and chemical properties. For example, the dioxin removal rate can reach more than 95% by using the method of carrying flow injection combined with bag dust removal. This method is easy to implement in engineering, has low cost and high removal efficiency. 

 In summary, activated carbon can effectively adsorb and eliminate dioxins through its unique pore structure and physical and chemical properties, and is widely used in flue gas purification in fields such as waste incineration power generation.
