Abstract:The manuscript discusses the role of polysaccharides and their derivatives in the removal of
metal ions from industrial wastewater. Quick modernization and industrialization increase the amount
of various heavy metal ions in the environment. Heavy metals can cause various diseases in humans
and also drastic environmental hazards. In this review, the recent advancement for the adsorption of
heavy metal ions from wastewater by using different methods has been studied. Various natural polymers
and their derivatives act as effective adsorbents for the removal of heavy metal ions from the
wastewater released from the industries and the treated water released into the environment can decrease
the probability of diseases in humans and environmental hazards. From the literature surveys, it
was concluded that the removal of heavy metal ions from industrial wastewater is beneficial for humans
as well as for environment. Graft copolymers act as the most efficient adsorbents for the removal
of heavy metal ions and most of these follow the pseudo-first-order and pseudo-second-order model of
kinetics.
