改性的石墨化碳黑填充色谱柱graphite Carbon black

改性的石墨化碳黑填充色谱柱graphite Carbon black 详细信息:


名称:改性石墨化碳黑

规格:3m*3mm

应用:

  1. 液化气分析

  2. MTBE分析

  3. C4分离


石墨化碳黑(GCB)是碳黑在惰性气体(通常为氩气)保护下加热到2700 ℃左右生成的一种碳材料。在高温条件下,碳黑内部和表面的大空隙结构被破坏,表面生成光滑、无孔的石墨晶型结构。因此GCB表面的碳原子之间都是SP2杂化,有单电子对和活泼离子,并具有六边形的微观结构。

  与碳黑和活性炭等材料不同,GCB表面总体表现为憎水性,可以吸附非J性和弱J性化合物;其次表面存在一些J性位点,使它能吸附J性化合物或做阴离子交换剂,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,对化合物表现出很广的吸附谱。

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.
