      改性的石墨化碳黑填充色譜柱graphite Carbon black

      改性的石墨化碳黑填充色譜柱graphite Carbon black 詳細信息:


      名稱:改性石墨化碳黑

      規格:3m*3mm

      應用:

      1. 液化氣分析

      2. MTBE分析

      3. C4分離


      石墨化碳黑(GCB)是碳黑在惰性氣體(通常為氬氣)保護下加熱到2700 ℃左右生成的一種碳材料。在高溫條件下,碳黑內部和表面的大空隙結構被破壞,表面生成光滑、無孔的石墨晶型結構。因此GCB表面的碳原子之間都是SP2雜化,有單電子對和活潑離子,并具有六邊形的微觀結構。

        與碳黑和活性炭等材料不同,GCB表面總體表現為憎水性,可以吸附非J性和弱J性化合物;其次表面存在一些J性位點,使它能吸附J性化合物或做陰離子交換劑,因此,它既可以吸附非J性和弱J性的化合物又可以吸附J性化合物,對化合物表現出很廣的吸附譜。

      Graphitized carbon black (GCB) is a carbon material produced by heating carbon black to about 2700 ℃ under the protection of an inert gas (usually argon). Under high temperature conditions, the large void structure inside and on the surface of carbon black is destroyed, and a smooth, non-porous graphite crystal structure is formed on the surface. Therefore, the carbon atoms on the GCB surface are all SP2 hybrids, with single electron pairs and active ions, and have a hexagonal microstructure.


        Different from materials such as carbon black and activated carbon, the surface of GCB is generally hydrophobic and can adsorb non-J and weak J compounds; secondly, there are some J sites on the surface, so that it can adsorb J compounds or act as an anion exchanger. Therefore, it can adsorb both non-J and weak J compounds as well as J compounds, showing a wide adsorption spectrum for compounds.
