Use of Phosphorus-Containing Polymers for the Removal of Metal Ions from Wastewater

The removal of heavy metals from various industrial waste effluents before discharging the effluent is a global environmental concern. In this chapter the advantages of the use of natural and synthetic chelating resins in the removal of various metal ions from aqueous solutions are presented. The chelating resins were obtained by the chemical modification of their surface with different phosphorus pendant groups. One may notice that the modification of the polymeric matrix through phosphorylation of its surface with different phosphorus pendant groups leads to an increase in the adsorption efficiency of the polymer in the removal of metal ions from various aqueous solutions. It was observed that the selectivity for various metal ions and the maximum adsorption capacity of the functionalized polymer depended on the type of the functionalized groups grafted on the polymeric matrix, the properties of the ion-exchange/coordination resin, and the phosphorylation conditions. In conclusion, the use of a functionalized polymer with various types of phosphorus pendant groups showed good feasibility in the removal of metal ions from different aqueous solutions.
