Removal Of Metal Ions

: Manuscript discussed about the role of polysaccharides and their derivatives in the removal of metal ions from industrial waste water. Quick modernization and industrialization increases the amount of various heavy metal ions in the environment. They can possess various disease in humans and also causes drastic environmental hazards. In this review the recent advancement for the adsorption of heavy metal ions from waste water by using different methods has been studied. Various natural polymers and their derivatives are act as effective adsorbents for the removal of heavy metal ions from the waste water released from the industries and the treated water released into the environment can decreases the chances of diseases in humans and environmental hazards. From the literature surveys it was concluded that the removal of heavy metal ions from the industrial waste water was important to decrease the environmental pollution and also diseases caused by the heavy metal ions. Graft copolymers were acts as most efficient adsorbent for the removal of heavy metal ions and most of these followed the pseudo first order and pseudo second order model of kinetics.

Sorption Method

Bio-absorption has an unparalleled advantage over other traditional methods in removing and recycling heavy metal ions from waste water. Consequently, it has a promising future. In this paper, the traditional methods and the bio-sorption method via which heavy metals are removed from waste water are compared to summarize the mechanism of bio-sorption, the types of bio-sorbent, the factors that can influence bio-sorption and the state of its application in waste water treatment .

In this study, heavy metal ions or organic in the aqueous solution are removed by adsorbent without filtration or centrifugation as well as incorporate magnetic materials into the adsorbent. A composite film GO/PVA from PVA and self – synthesized GO by co - precipitation method has synthesized successfully. This composite was characterized by XRD, SEM, FT-IR to evaluate the properties of this material. The results showed that there was an interaction between GO and PVA so we have tested the adsorption capacity of this composite with Co(II) ions and the obtained efficiency of this process was 99.5% with the initial concentration of solution is 20 mg.L-1. This film is completely capable of removing heavy metal ions from waste water.
