Carbon nanomaterial-based aerogels for improved removal of copper(II), zinc(II), and lead(II) ions from water

Access to clean water continues to be an issue throughout the world. Supplies of freshwater have been decreasing due to population growth, natural disasters, and pollution. Advanced carbon-based technologies have allowed for opportunities at the advancement of efficient and cost-effective materials to quickly and easily remove contaminants from high demand drinking water areas. Carbon nanomaterials that were integrated into 2-D hybrid papers have previously shown the ability to adsorb metal ions, such as copper (II), and polyaromatics. This work highlights the advantages of using carbon-based aerogels for removing metal ions, specifically copper, lead, and zinc, from water. The use of single-wall carbon nanotube- graphene nanoplatelet (SWCNT - GnP) aerogels with 3-D architecture have shown the increased adsorption of polyaromatic compounds. Herein we demonstrate their increased ability to adsorb copper (II), lead (II), and zinc (II) ions. Compared to SWCNT - GnP hybrid papers and activated carbon, carbon nanomaterial-based aerogels have an adsorption capacity, q, of up to 5-fold, 7-fold, and 48-fold larger for copper, lead, and zinc, respectively.
