Dynamic Adsorbents | What Is

Alumina oxide is an inorganic substance made by the dehydration of alumina hydroxide Al (OH)3 at high temperatures. The active sites used for separation consist of acidic alumina ions, basic oxide ions and polar Al-OH groups. The unsaturated alumina ions act as Lewis acids, and the Al-OH groups act as dipoles. The hydroxyl groups at the surface

Tips And Tricks For The Lab: Column Packing -

Jun 05, 2012  Alumina is slightly basic, so will retain acidic compounds more strongly. It is good for separation of components that are weakly or moderay polar and the purification of amines. Absorbent particle size affects how solvent flows through the column. Silica or alumina are both available in a variety of

“Alien Vs. Predator”… Or In Other Words “Silica Vs.

The loading capacity of Alumina (140-170 m2/g) is lower than the loading capacity of Silica ( 400-500 m2/g ). Nonetheless, it has amphoteric properties and is therefore available in three different types: neutral, acidic and basic. The neutral type of Alumina allows purifying in a pH neutral environment, useful for acid or also basic sensitive
