Progress and perspectives for the use of pillared clays as adsorbents for organic compounds in aqueous solution

The world is faced with several problems as regards water pollution. This is due to several factors, including the discharge of effluents into the environment with no prior treatment. This wastewater, therefore, contains significant levels of pollutants, including numerous toxic organic contaminants and others that are similarly undesirable. Several studies have attempted to find ways of removing wastewater contaminants using pillared interlayered clays (PILC) as adsorbents. In this work, we present a summary of those studies that have used PILC as adsorbents for the removal of organic compounds from aqueous solutions while simultaneously illustrating their potential for this purpose. A general overview is provided so that the reader can acquire a basic understanding of the PILC and their modified counterparts that have been used, and some of the characteristics that can directly affect their adsorption behavior, especially their textural and surface properties.
