The three performance indicators play a very important role in the selection and application of activated carbon. The physical performance indicators are: shape, appearance, specific surface area, pore volume, specific gravity, mesh number, particle size, abrasion resistance, floating rate, etc. Chemical performance indicators are: PH value, ash, moisture, ignition point, uncarbonized matter, sulfide, chloride, cyanide, sulfate, acid soluble matter, alcohol soluble matter, iron content, zinc content, lead content, arsenic content, calcium Magnesium content, heavy metal content, phosphate, etc.
Adsorption performance indicators are: methylene blue adsorption value, iodine adsorption value, phenol adsorption value, carbon tetrachloride adsorption value, caramel adsorption value, quinine sulfate adsorption value, saturated sulfur capacity, penetration sulfur capacity, water capacity, chlorine Ethane vapor protection time, ABS value, etc. The higher the adsorption value, the better the performance of activated carbon. So how to easily identify the level of activated carbon adsorption without detection equipment? Here are some easy methods for reference. 1.
Directly look at the indicators provided by the manufacturers. The commonly used adsorption indexes of activated carbon are: iodine adsorption value, carbon tetrachloride (CTC) adsorption value, methylene blue adsorption value. The iodine adsorption value is used to indicate the adsorption capacity of activated carbon to liquid substances. Carbon chloride adsorption value is used to indicate the adsorption capacity of activated carbon to gaseous substances, and methylene blue adsorption value is used to indicate the decolorization ability of activated carbon.
The higher these graphite electrode suppliers indicators, the stronger the adsorption capacity of activated carbon. Therefore, when you buy activated carbon, you can choose the activated carbon suitable for your own use in combination with these indicators provided by the manufacturer. 2. Look at the volume: As mentioned above, if you want to improve the adsorption performance of activated carbon, you can only make the pore structure on the activated carbon as much as possible.
