Standard Activity I – Activated Alumina

Labs use Alumina, Standard Activity I as a versatile all-purpose adsorbent for lab and process applications.

• See “Determination of Activity using the Brockmann and Schodder Test” for measuring the precise activity of alumina

The starting activity level of Alumina, Standard Activity I is about half as high as Alumina, Activity Super I and can be deactivated by the addition of polar media (water, alcohols, etc.) according to the deactivation scale.

• See “Deactivation of Alumina” for the deactivating aluminas method
• Standardized manufacturing processes provide a specific Brockmann dryness level for lot to lot reproducibility and precise deactivation possibilities
• The Loss on Ignition (LOI) is 1.7 +/- 0.2% and specific surface is ~150 m²/g.

1. Acidic
2. Neutral
3. Basic

The adsorption behavior is extremely constant. Alumina, Standard Activity I may be used for the purification of solvents.
