More and more interests are focused on developing these plant
residues as biosorbent for wastewater treatment due to their relative
high sorption affinity with POPs, ubiquitous presence in the
environment, and ease being modified to materials with higher
efficiency. Chung et al.
found brown seaweed (Sargassum
hemiphyllum) powder showing high phenanthrene removal
efficiency at different conditions and it was viewed as a potential
candidate for tackling POPs pollutions.
