Abstract
Zeolites having surface modification with graphene oxide, reduced graphene oxide, or a sulfide have utility in removing pollutants from a water supply. Pollutants include Persistent Organic Pollutants (POPs) and heavy metals, such as lead. POPs are adsorbed onto zeolites having surface modification with graphene oxide and/or reduced graphene oxide. Heavy metals are adsorbed onto zeolites having surface modification with a sulfide.
