The Adsorption of Organic Pollutants by Gemini Surfactant-Modified Montmorillonite from Water
Journal Title: Modern Approaches in Oceanography and Petrochemical Sciences - Year 2018, Vol 1, Issue 2
Abstract
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 [1]. 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 [1]. 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 [2].
