Silica gel - Wikipedia
History. Silica gel was in existence as early as the 1640s as a scientific curiosity. It was used in World War I for the adsorption of vapors and gases in gas mask canisters. The synthetic route for producing silica gel was patented by chemistry professor Walter A. Patrick at Johns Hopkins University in 1918.. In World War II, silica gel was indispensable in the war effort for keeping
Adsorption and desorption of silica gel circulating
1. Introduction. Dehumidification methods in general can be divided into condensing dehumidification and adsorption material dehumidification , , .Adsorption material, such as silica gel, usually comes in the form of a packed bed in public dehumidification air conditioning systems , .Although it lowers the cost of the packed bed, dense packing causes large pressure drop and increased the
Synthesis and Characterization of Alginate–Silica Gel
Dynamic water adsorption test showed that the composite with a sodium alginate-to-silica gel mass ratio of 5:1 possessed the best water adsorption kinetics. Water adsorption quantity difference of the composite between a typical adsorption condition (80% RH) and a regeneration condition (30% RH) is more than twice that of silica gel.

WO2017015728A1 - Method for producing an adsorption agent
Method for manufacturing an adsorption agent for treating compressed gas, whereby this method comprises the following steps: — the provision of a monolithic supporting structure; - the production of a coating suspension that comprises an adsorbent; - the application of the aforementioned coating suspension on the aforementioned supporting structure to form a coating; - the application of a
EVALUATION OF CaCl 2–SILICA GEL SORBENT FOR WATER SORPTION
A salt in silica gel sorbent consolidated with graphite flakes and binder was also analyzed. The sorbents were evaluated with a volumetric nitrogen physisorption porosimeter and thermo-gravimetric water vapor sorption analyzer. The hygroscopic salt filled 56–60% of the open pore volume of the mesoporous silica gel supports.
Silica Gel: Passive Control of Relative Humidity
Example: Conditioning the silica gel to equilibrium moisture content at 50% RH. According to Appendix 2, 27.07% water (EMC % g/g dry weight) is needed in regular silica gel to be in equilibrium at 50% RH. If you start with 1000 g of dry silica gel, introduce water until the weight of the humid sorbent reaches 1270.7g (1000 x 1.2707).
Selective Removal of Arsenic(V) from Aqueous Solution
A new surface-ion-imprinted amino-functionalized silica gel sorbent was prepared by the surface imprinting technique with As(V) as the template, 3-(2-aminoethylamino)propyltrimethoxysilane as the functional monomer, silica gel as the support, and epichlorohydrin as the cross-linking agent and was characterized by FTIR, SEM, nitrogen adsorption, and the static adsorption–desorption experiment

An ion-imprinted amino-functionalized silica gel sorbent
A new ion-imprinted amino-functionalized silica gel sorbent was synthesized by the hydrothermal-assisted surface imprinting technique using Cd 2+ as the template, 3-[2-(2-aminoethylamino)ethylamino]propyl-trimethoxysilane (AAAPTS) as the functional monomer, and epichlorohydrin as the cross-linking agent (IIP-AAAPTS/SiO 2) for the selective removal of Cd 2+ from aqueous solution, and was
