Abstract
The pollution of water sources with toxic metal ions is a thoughtful subject. Numerous aquatic systems are polluted with dissimilar toxicmetal ions from various industrial effluents and anthropogenic activities. Water treatment seems to the chief environmental test. The sorption is the best effective method for metal ions elimination in water. Currently, graphene and its composite materials are attaining significance as new generation nano-sorbents. Graphene is a two dimensional nanomaterial with single layer of graphite. These have achieved a great reputation in water treatment because of their distinctive physico-chemical features. The present chapter describes the elimination of metal ions using graphene and its composite materials. The emphasis has been made on syntheses, applications, regeneration and recycling and future perspectives. Definitely, this chapter will be valuable tool for researchers, government authorities and academicians.
