| Product Name | Tris (tris base) for modified activated carbon applications, CAS 77-86-1 |
| Catalog No. | ATR-B-YJL-0286 |
| Description | Tris(hydroxymethyl)aminomethane, commonly known as Tris or tris base, is a high-purity biological buffer with a purity above 99%. Beyond its classical role as a buffering agent, Tris can be applied in the modification of activated carbon to improve both its adsorption performance and chemical stability. Activated carbon offers a high specific surface area and strong general adsorption capacity, but its limited number of surface functional groups restricts its affinity for certain substances. Modification with Tris introduces additional functional groups onto the carbon surface, enhancing adsorption toward target compounds. Tris modification also improves the chemical stability of activated carbon, which is otherwise prone to oxidation or corrosion in aggressive chemical environments, thereby extending its service life under harsh conditions. The modified material is widely applicable in fields such as air purification and water treatment. |
| Intended Use | Used as a surface modifier for activated carbon to increase surface functional group density, enhance adsorption capacity toward specific substances, and improve chemical stability for applications such as air purification and water treatment; also serves as a biological buffering agent. |
| Principle / Technology | Tris reacts chemically with the surface of activated carbon under controlled heating, forming new functional groups. These groups increase the number of active adsorption sites and improve resistance to oxidation and corrosion, resulting in modified activated carbon with higher adsorption performance and stability. |
| Reaction Conditions / Protocol | Mix powdered activated carbon with Tris and heat the mixture to a defined temperature. Control the reaction conditions so that Tris undergoes chemical reaction on the activated carbon surface, generating new functional groups. The resulting modified activated carbon exhibits improved adsorption performance and chemical stability. Note that the specific preparation method and application parameters may vary with different requirements and should be established through targeted research and experimental validation. |
| Package Specifications | 25 kg/drum |
| Purity | >99% |
| Application Notes / Precautions | Tris is a chemical substance; observe all relevant safety regulations and operating procedures during handling and use to ensure safety and effectiveness. The optimal modification protocol and application scenario should be verified experimentally for each specific use case. |
| Alias | tris base |
| CAS Number | 77-86-1 |
