Abstract Bentonite is a naturally occurring material with planar posite , which is widely modified through
intercalated processes to form multifunctional sorbents. The bentonite based sorbents are highly attracted to anic
pollutants in environments due to environmental friendly , high efficiency and cost effective. Recently , the progress in
sorption mechanisms of modified bentonite , which are highlighted in this review , has been made to extend their
environmental applications. The recent applications in abating anic pollutants are briefly summarized , including
wasterwater treatment , air pollution control , contaminated soil remediation , and preparation of clay based environmental
catalyst. The potential research areas are also prospected.
