A high density of silanol groups dominates the silica surface which can be functionalized with a wide variety of organic functional groups [99].
The results showed that adsorption capacity was affected by the organic functional group nature, thus the quaternary ammonium-functionalized SBA-15 has remarkably high adsorption capacity (63 mg/g) compared to mono one (55 mg/g).
Fortunately, analytical schemes have been carefully worked out for all the common inorganic ions and organic functional groups.
An example of a chemical reaction that can be used to identify organic functional groups is the reaction between bromine in a carbon tetrachloride solution and organic compounds containing carbon-carbon double bonds.
The peaks that appeared obviously belong to the organic functional groups of the synthesized precursor.
This result confirmed that all organic functional groups were anchored on the surface of MSNs.
Soil organic C, recalcitrant C and organic functional groups showed no significant differences among treatments.
The results confirmed the successful graft of organic functional groups on the MCM-48 surface.
This review focuses on the recent development of organic functional materials employing azulene unit.
A Nexus 470 Fourier transform infrared spectrometer (NICOLET, USA) was employed to observe the changes of organic functional groups.
However, as an organic functional small molecule, perylene bisimide tends to be cleared from the blood circulation quickly.
