<p>Formaldehyde (FA) is an extremely active compound that is widely used in numerous<br>
applications. Given that FA is a known carcinogen, it is essential to remove it from the environment.<br>
Titanium dioxide (TiO2), due to its special physicochemical properties, is a promising adsorbent for<br>
the removal of specific organic compounds from aqueous solutions. In this study, the interaction of<br>
TiO2 with FA in the presence and absence of quartz sand, the most common mineral on the Earth’s<br>
surface, was investigated under static and dynamic (batch) conditions, at 25 C. The experimental<br>
data suggested that the sorption of FA onto TiO2 can be described adequately by a pseudo-second<br>
order kinetic model, indicating that the main sorption mechanism was chemisorption. It was<br>
observed that the combination of TiO2 and quartz sand could1 lead up to effective removal of FA<br>
from aqueous samples.</p>
