| titleOfInvention | Activated carbon fiber adsorbent, preparation method thereof and application thereof in benzene series adsorption |
| abstract | The invention provides a preparation method of an activated carbon fiber adsorbent, belonging to the field of volatile organic compound treatment. Mixing a boron precursor, a water-soluble nitrogen-containing organic matter, an active assistant, a surfactant and water to obtain a mixed solution, wherein the active assistant is glucose, citric acid or ascorbic acid; the boron precursor is m-aminobenzene boric acid, p-aminobenzene boric acid, m-cyanophenyl boric acid or p-cyanophenyl boric acid; and mixing the mixed solution with the activated carbon fiber, and then carrying out hydrothermal reaction to obtain the activated carbon fiber adsorbent. The activated carbon fiber adsorbent prepared by the invention can generate a fluffy boron-doped nitrogen carbide coating which has a nano size, is uniformly distributed, has high boron element content and takes an active B-N bond as a main form on the surface of activated carbon, greatly improves the content of boron and nitrogen elements on the surface of a carbon material, improves the adsorption and desorption performance of the activated carbon fiber adsorbent to a benzene series substance, and can greatly improve the cycle adsorption performance of the activated carbon fiber adsorbent. |
