Plant residues which mainly derived from wood-processing
industries, agricultural production, and tree harvesting and pruning,
is a ubiquitous green waste in the environment and may cause
some serious environmental pollution
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 [8,18,20].
