Series
of
β-cyclodextrin
(β-CD)-based
magnetic
hyper-crosslinked
polymers
(CD-gs-MHCPs)
were
synthesized
by
crosslinking
β-CD-graft-styrene
(CD-gs)
with
different
rigid
crosslinkers,
which
delivered
superior
adsorption
performance
for
triazine
herbicides
(THs).
The
mechanism
study
revealed
that
the
effective
CD-gs-MHCP
THs
can
be
ascribed
to
hydrogen
bonds,
hydrophobic
interaction,
π-π
stacking
interaction
and
pore
adsorption.
Combined

was
successfully
achieved.
