Problem description:

Charcoal (C) can adsorb colored and odorous impurities in water and air because it has many small holes. But these pores should have been filled with air or water, why can they be adsorbed? Why do you specifically absorb colored and odorous impurities instead of water or air?

Analysis:

Modern legend of activated carbon purification history

Activated carbon is a very good adsorbent, which is made from charcoal, various fruit shells and high-quality coal by physical and chemical methods, and through a series of processes such as crushing, screening, catalyst activation, rinsing, drying and screening. During World War I and World War II, it was a magical weapon against poisonous gas. The mysterious guardian of the gas war during the Cold War; People's faithful health protection during SARS; The most important raw material for chemical industry and daily purification, but it always exists in the form of powder or granules, which is difficult to preserve, aging for a short time and easy to pollute, thus restricting its development and application. The birth of Supreme Black Diamond Block Activated Carbon not only solved the technical problems of forming activated carbon, but also retained its super-strong physical adsorption principle, thus becoming a real activated carbon application technology with long-term purification function! As the third-generation brand-new technology of activated carbon, it inherits and promotes all purification functions of activated carbon. It is a perfect representation of the history of activated carbon purification, and also a modern legend of the history of activated carbon purification!

The Mysterious Source of Purification —— Van der Waals Force

The supreme black diamond is combined by the principle of physical adsorption, that is, by van der Waals force when molecules collide with molecules of adsorbed substances. The greater the collision probability, the stronger the adsorption force! Collision probability is related to temperature, pressure, gas velocity and gas concentration. Under normal circumstances, oxygen molecules can be filtered through its unique pore structure, and other toxic heavy molecules can be adsorbed, such as benzene (C6H6), formaldehyde (CH2O), toluene (C6H5CH3), methane (CH4), carbon monoxide (CO), carbon dioxide (CO2), chlorine (Cl2), ammonia (NH3) and radon (Rn).
