Cleanert Alumina N sorbent (pH = 7.5) can adsorb molecules by interaction with the aluminum metal center. The neutralized surface allows interaction with compounds whose heteroatoms are electronegative (e. g. N, S, P) or with an electron-rich highly aromatic structure. This material is generally used in the detection of pigment such as Sudan and malachite green.
