The specific surface areas of natural bentonite and DAHbentonite
were determined as 67.49 and 109.95 m2 g1, respectively.
The increase of the surface area induced by the incorporation
of 1,6-diaminohexane molecules between the silicate layers
is mainly caused by the presence of the micropores produced in the
interlayer spaces. These results also indicate that natural bentonite
was successfully modified with DAH.
