Fixed bed adsorption of diquat dibromide from aqueous solution using carbon nanotubes

Abstract

While carbon nanotubes (CNTs) are increasingly studied as attractive adsorbents for wastewater treatments, research on adsorption characteristics of these materials is mostly restricted to batch studies. However, it is well known that continuous flow techniques can be more efficient in removing contaminants. The present work exploits the attributes of different types of CNTs in a fixed bed column for the dynamic uptake of diquat dibromide from aqueous solutions.
