General description

Aluminum oxide (Alumina) was used as an adsorbent in TLC. It can be prepared by calcination of aluminium hydroxide in moderate temperature followed by washing. The adsorbent is backed on glass plates to perform TLC.
It is also evident that the amount of water affects the chromatographic behavior of alumina during TLC. There are three types:
a. Acidic
b. Basic
c. Neutral

Application

Aluminum oxide on TLC-glass plates may be used for TLC and HPTLC.
