Adsorbents, Filter Aids and Drying Agents

Molecular sieves, 3 Å.

Choosing a Molecular Sieve: 1. The preferential adsorption of one molecule over another depends upon pore diameter and mesh size. 2. The dynamic capacity of the silica gel for adsorbing a particular compound is governed by the internal surface area:

Molecular sieves, 3A.

Molecular sieves are crystalline metal aluminosilicates having a 3-dimensional interconnecting network of silica and alumina tetrahedra. Natural water of hydration is removed from this network by heating to produce uniform cavities which selectively
