A small peak at 1631 cm-1 is due to deformation vibrations of adsorbed water
is kind of like a fourth state of matter (Figure 3).
In the plastic package, however, the powder adsorbed water
because of the inefficient barrier, and the water easily bound with the low-molecular weight molecules (fructose, glucose and sucrose) present in the juice in powder.
The band observed at 3460 cm-1 and 3437 cm-1 were assigned to O-H stretching vibrations of adsorbed water
When heated, the desiccant releases its adsorbed water
molecules, which are purged to the atmosphere.
Dehydration reactions involving loss of adsorbed water
and destruction of structural OH during kaolinite dehydroxylation is considered to have accounted for the observed mass losses.
The hydrated sample was removed, ground in a mortar and evacuated at 260[degrees]C to remove physically adsorbed water
from the surface.
It shows that montmorillonite lost about 14% of its original weight up to 120[degrees]C because of the removal of physically adsorbed water
then becomes stable till 500[degrees]C.
But results showed that adsorbed water
for modified bagasse lower than raw bagasse in same particle size because of modification process with acetic anhydride replaces a hydrophobic functional group in the raw bagasse structure and improve hydrophobic and oleophilic properties of bagasse.
5% adsorbed water
and does not require drying prior to compounding.
Smectites are a specific type of clay mineral that expands and contracts with adsorbed water
1) and Lycatab showed an initial broad endotherm below 100[degrees]C, due to loss of adsorbed water
