Recycling Plastic Waste for Environmental Remediation
in Water Purification and CO2 Capture
Posted on 2020-06-16 - 00:03
The
synthesis of hyper-cross-linked polymers (HCPs) is typically
achieved using costly reagents. This study demonstrates the utilization
of a plastic waste, Styrofoam, to create a series of HCPs through
a one-pot Friedel–Crafts reaction. The influence of substrate,
catalyst, and cross-linker ratio was investigated to yield HCPs with
Brunauer–Emmett–Teller (BET) surface areas up to 1199
m2/g. We exploited this recyclate HCP for carbon capture
from flue gas, dye removal, and As(V) sequestration from water. The
adsorption capabilities of this cost-effective adsorbent were comparable
to and surpassed current state-of-the-art nanoporous materials such
as metal–organic frameworks (MOFs), activated carbon, zeolites,
and other HCPs.
