1. Iodine adsorption value: The iodine adsorption value is an important physical indicator of columnar activated carbon. The iodine adsorption value of nut shell charcoal, bamboo charcoal, and coal-based charcoal is between 500-1200, and the iodine value of activated carbon material is from 800 to 850. 900, 950, 1000, 1100mg/g and so on, the adsorption capacity is also different, the grid is also very different! Activated carbon with the same iodine value has a good effect due to the large specific surface area.

2. Use weighing to compare weight: In order to improve the iodine adsorption performance of activated carbon, more pore structure should be made on the surface of activated carbon as much as possible. coconut activated charcoal The more pore structure, the lighter the activated carbon, the lower the density, and the lighter the relative density. Therefore, the excellent activated carbon feels lighter in the hand. In the case of the same weight packaging, the activated carbon with excellent performance will be much larger than the activated carbon with relatively poor quality.

3. Look at the air bubbles in the water: Put a small amount of activated carbon into the water. Due to the penetration of water molecules, the water molecules will gradually immerse into the micro-pore structure of the activated carbon, allowing the air in the pores to be discharged, thereby generating a series of extremely fine bubbles , The columnar activated carbon manufacturer forms a series of bubble lines in the water, and at the same time it emits tiny bubbles, which is very interesting. The more this phenomenon occurs in the columnar activated carbon manufacturers and the longer the duration, the better the adsorption of activated carbon.

4. Look at the decolorization ability of methylene blue: another manifestation of the adsorption capacity of activated carbon is the decolorization ability of methylene blue. The microporous structure of activated carbon has the outstanding characteristic of turning colored liquids into light or colorless. This is actually because the columnar activated carbon can adsorb A phenomenon caused by pigment molecules in colored liquids.

5.Important reminder: At present, consumers do not know enough about activated carbon. Sometimes they regard unactivated bamboo charcoal, charcoal, coconut shell charcoal and other carbonized materials as activated carbon products. activated charcoal pellets for odor Secondly, they regard low adsorption value carbon carvings and ordinary activated carbon as high-quality Activated carbon. Therefore, please make a distinction when purchasing and beware of being deceived.
