1. A process for producing a functionalized activated carbon product, comprising:
a. creating grafting sites on a surface of an activated carbon product to yield a precursor activated carbon product by i. creating reactive sites on the surface of the activated carbon product, and ii. attaching cis-9-octadecen-1-ol to the reactive sites to provide the grafting sites;
b. exposing the precursor activated carbon product to at least a first vinyl monomer; and
c. initiating a polymerization reaction to graft at least the first vinyl monomer to the grafting sites and to polymerize at least the first vinyl monomer, to yield the functionalized activated carbon product, wherein the functionalized activated carbon product comprises the activated carbon product grafted with a polymer of at least the first vinyl monomer.
