Details 4A Molecular sieve is a material with single and accurate minute pore, the diameter of host crystal pore is 4Å(1Å=10-10m), can be used to adsorb gas or liquid. The small molecules can be adsorbed through the pores, while the larger molecules can not. A molecular sieve can absorb up to 22% of its own weight of water.
