What is adsorption?

adsorption is a process similar to absorption that the substance in the gas or liquid connects to the solid. The substance can be a pollutant called adsorbate, which is attracted to the surface of a special solid. Adsorption occurs naturally, but industrialists have improved adsorption methods to clean hazardous waste or clean drinking water. These small particles can be separated from this phase called adsorbent to enter another phase. The material of another phase, such as solid carbon, preferably targets these particles and adsorbed to its surface. The remaining air or liquid has been cleaned. This differs from absorption, where particles never change the phase, but enter the pores of solids together with accompanying air or water.

Natural or organic methods adsorpce to all the time. For example, the ocean adsorbs carbon dioxide in the atmosphere that affects the climate and atmospheric temperature. Soon people remarked that if they were storking a piece of bone all the way they could put the bone in a mixture of food, such as sugar water, and would collect polluting particles that were not edible, thereby cleansing the food. The particles colored in our visible spectrum, as well as particles with strong odor, are the simplest adsorb.

It is important to take advantage of the power of adsorption to fight modern chemical risks. Some solids are ideal for adsorption. They have a lot of surface surfaces because of their volume because micropór is marked. Industrial and commercial use of adsorption filters varies. For example, carbon will improve the taste of cold drinking water. The carbon filter can be heated to clean the surface of adsorbates and re -use. Activated alumina Removes harmful chemicals such as fluoride and arsenic of liquids. Synthetic resins can clean highly dangerous leaks such as nervous gas, in areas that could have high temperatures, such as explosives.
