As an economical and efficient method, adsorption technique
by activated carbon is widely applied to remove antibiotics and
heavy metal ions from wastewaters [6,9,10]. Previous studies were
conducted to investigate the adsorption of CIP [11] and Ni(II) [8]
from aqueous solution by activated carbon separately. As we know,
the water body is a complex system where antibiotics and heavy
metal often coexist due to influxes of various pollution sources.
Little attention has been given to investigate the adsorption of
antibiotics on activated carbon in aqueous solution as affected by
heavy metals. Similarly, few studies have been reported about the
effect of heavy metals on activated carbon in aqueous solution as
affected by antibiotics.
