摘要：
Access to clean water continues to be an issue throughout the world. 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. The use of single-wall carbon nanotube-graphene nanoplatelet (SWCNT-GnP) aerogels with a 3-D architecture has led to 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 (AC), carbon nanomaterial (CNM)-based aerogels have an adsorption capacity, q, that is up to 5-fold, 7-fold, and 48-fold larger for copper, lead, and zinc, respectively.
