The activated carbon adsorption method for treating indoor pollution is currently the most widely used, mature, safe, effective, and diverse method for absorbing substances. Although there are many varieties of activated carbon in terms of appearance and usage, they share a common characteristic of "adsorption".
How to easily identify the high or low adsorption value of activated carbon?
At first glance, the density: when weighed by hand, the more pores there are in activated carbon, the higher the adsorption performance, the lower the density, and the lighter the hand feel. Second look at bubbles: Put a small handful of activated carbon into water to generate a series of extremely small bubbles, pull out a small bubble line, and at the same time make a faint sound. The more severe and long-lasting this phenomenon occurs, the better the adsorption capacity of activated carbon. Three checks on decolorization ability: Place activated carbon in colored water in an amount equal to or greater than half of the water to achieve a more significant effect. After allowing it to stand for 10-20 minutes, compare it with a control water sample. Under the same conditions, the stronger the decolorization effect, the better the adsorption capacity of activated carbon.
Activated carbon with the same material and purpose may have different inner pore sizes. Generally speaking, the quality of high-quality activated carbon adsorbing harmful substances can approach or even reach its own quality.
