The Adsorption of Organic Pollutants by Gemini Surfactant-Modified Montmorillonite from Water by Zhenghua Wang in MAOPS- Lupine Publishers
Water is a very important resource to human life and the
development of society. But large amounts of natural and
anthropogenic organic substances are constantly discharged to
water bodies. The serious problem of water pollution has been
raising a global concern. These typical organic contaminants in
water environment include but not limited to dyes, pharmaceuticals
and personal care products (PPCPs), phenols and polycyclic
aromatic hydrocarbons (PAHs). Most of those compounds are
toxic to aquatic biota and human beings. Therefore, removal
of this organic matter from water is a great subject of research
nowadays. Off all the removal methods, adsorption is an effective
technique which is widely used. Various adsorbents have been
studied that include materials based on carbon, clay minerals,
polymers, silica, and so on . Clay minerals are considered as low
cost and easily available adsorbents. Montmorillonite, a 2:1 layered
dioctahedral aluminosilicate of smectite group clay, is one of the
most investigated clay minerals for removing organic pollutants
because of its versatility and facile modification of its porosity,
acidity, hydrophilicity, and so on.
