Interaction of Titanium Dioxide with Formaldehyde in the Presence of Quartz Sand under Static and Dynamic Conditions

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