Study on the Adsorption of Cyanide Chloride in Typical One-Dimensional Porous Molecular Sieves

초록

Cyanogen Chloride (CNCl) is a cyanide poison that can cause harm to human health and the environment if directly discharged into the air. In order to explore the adsorption mechanism of CNCl on typical one-dimensional porous molecular sieves AEL, AFO, EUO, SSY, TON and VFI, the free volumes of these six molecular sieves were calculated, and their adsorption isotherm and isosteric adsorption heat were analyzed. The results indicate that VFI molecular sieves have the relatively largest free volume and may have the best adsorption effect on small gas molecules. VFI molecular sieve has the highest adsorption quantity for CNCl, and its adsorption capacity is stronger. VFI molecular sieve can release an equal amount of adsorption heat while adsorbing more CNCl molecules, which also indicates that VFI molecular sieve has stronger adsorption capacity
