Introduction to Tris
Tris(hydroxymethyl)aminomethane is also abbreviated as tris, CAS77-86-1, alias tromethamine, ammonium tromethamine, trimethylaminomethane, is a commonly used biological buffer, conventionally produced as white crystalline powder, PH value Weak base, the buffer range is between 7.0-9.2.
Application of Tris in activated carbon
Modern people pay more and more attention to the quality of life, but many living environments and office environments have more or less harmful gases such as formaldehyde and benzene. The use of activated carbon has become the choice of many people, using activated carbon to adsorb these harmful gases. Among them, tris is used as modifier, and then through hydrothermal reaction, the denatured activated carbon is better used in life.
Preparation method of Tris in activated carbon
What is introduced here is the method of adsorbing trace sulfur dioxide by modified activated carbon fiber, which belongs to gas adsorption and separation technology. Using tris, serine, alanine, etc. as the basis to make modifiers to treat viscose activated carbon fibers, through hydrothermal reaction under fixed conditions, to prepare chemically modified activated carbon fibers with a large number of amino groups on the surface.
Preparation by this method has the following advantages: (1) Small molecules are used to ensure the modification of the modifier surface, and the high ratio of activated carbon fiber is maintained, so that the porous structure in the activated carbon will not be destroyed, thereby better adsorption The harmful substances in the air increase the amount of adsorption; (2) This method is relatively mild, has less pollution, is easy to scale up production and guarantees the environment to a certain extent; (3) Use tris (hydroxymethyl) aminomethane and other chemical reagents to modify After modified activated carbon, its adsorption capacity can be increased to 40-60mgSO2/g adsorbent, which is 4-6 times higher than before modification.
Desheng tris meets the requirements for activated carbon modification
In fact, the number of tris manufacturers on the market is decreasing, not only because of the relatively serious safety accidents in 2019, but also because of the emphasis on the environment, many manufacturers actually cannot meet certain requirements. Desheng Biochemical has been testing tris since 2012. It has a professional R&D team, and has accumulated experience in continuous experiments. According to market requirements, it has invested in pilot and large-scale trials, and it has the current large-scale production. The amino methane products are adapted to various needs, and there is no problem with modified activated carbon. Special indicators can also be customized! The quality of a manufacturer can be seen from the receipt of the goods, Desheng welcomes your consultation!
