well Activated carbon We can start from the following aspects. The detailed explanation is as follows

Look at bubbles. Put a small amount of activated carbon into water. Due to the infiltration of water, the water will gradually immerse into the pore structure of activated carbon, forcing the air in the pores to be discharged, resulting in a series of small bubbles. Pull out a small bubble line in the water, and at the same time, it will make a faint bubble sound, which is very interesting. The more intense this phenomenon occurs and the longer it lasts, the better the adsorption of activated carbon will be.

See decolorization ability. activated carbon adsorption Another performance of the ability is the decolorization ability. Activated carbon has the ability to turn colored liquid into light color or colorless, which is actually caused by the adsorption of pigment molecules in colored liquid by activated carbon. Because of this characteristic, activated carbon is widely used in the production process of brown sugar to white sugar in the sugar industry. Take two transparent cups, put pure water in one cup, and then drop a drop of red ink (any pigment that is easy to observe but does not change the nature of the water can be used here, such as blue ink, printer color ink, but ink and carbon ink cannot be used). After mixing evenly, pour half of the colored water into another cup for comparison. Put activated carbon into colored water, the amount should reach half or more of water, so the effect will be more obvious. After standing for 10-20 minutes, compare with the reference water sample. Under the same conditions, the stronger the decolorization effect, the better the adsorption of activated carbon.

See the volume: to improve the adsorption performance of activated carbon, it is only necessary to make as many pore structures on activated carbon as possible. The more pores, the looser the activated carbon, and the lighter the relative density will be. Therefore, good activated carbon will feel lighter. Under the condition of the same weight of packaging, the volume of high-performance activated carbon will be much larger than that of low-quality activated carbon. At the same time, because the friction between carbon particles is easy to form black powder.
