Abstract
Official abstract text for this publication.
A metal adsorbent that includes silver-decorated graphene nano-platelets and a polymer matrix that comprises polyamide, wherein the metal adsorbent is a highly porous material with a specific surface area of 200 to 300 m2/g and an average pore size of 50 to 100 Å, which effective removes heavy metals and cations from a liquid. Various embodiments of the metal adsorbent and a method of making thereof are also provided.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of reducing a heavy metal content of a liquid containing one or more dissolved metals, comprising: passing the liquid through a column packed with particles of a nanocomposite material to adsorb at least a portion of one or more heavy metals onto the nanocomposite material, wherein the nanocomposite material comprises: a polymer matrix comprising a polyamide: and silver-decorated mayhem nano-platelets that are dispersed in the polymer matrix, wherein the polvamide comprises reacted units of an aromatic amine and an acyl halide; and wherein said one or more heavy metals are at least one selected from the group consisting of mercury, chromium, cadmium, lead, nickel, copper, and cations thereof. 2. The method of claim 1 , wherein the liquid is passed through the column packed with the particles of the nanocomposite material in a continuous fashion.
