Effect of heat on the adsorption properties of silica gel
(Journal article; Peer reviewed, 2012)Adsorption properties of silica gel have been attributed to the surface hydroxyl groups of silica gel. Some hydroxyl groups are free standing and called free silanol groups. Some are hydrogen bonded to neighbouring silanol ... -
Near infrared spectroscopic study on the adsorption of methanol on silica gel
(Journal article; Peer reviewed, 2013)The silanol groups on Silica gel surface are sites for adsorption of polar molecules. Alcohols and other polar molecules are easily adsorbed by forming hydrogen bondings with OH groups on silica gel surface. A study on the ... -
The nature of rest silanol groups on the surfaces of silica based solid phase extraction materials
(Journal article; Peer reviewed, 2013)Chemically bonded solid phase materials are very important in separation chemistry. The chemically modified silica gel contains rest silanol groups that can affect the retention properties when they are used for separation ...
