A new granulated sorbent based on acrylonitrile: Synthesis and physico-chemical properties

Abstract

It was common practice in water treatment procedures to employ functional polymers to sorb metallic species from the water. Due to the wide spectrum of potential functional groups on polymeric backbones, these sorbents had the potential to separate a huge range of metals. The characteristics of the cationic metallic ions and the functional groups were closely related to the selectivity and sorption efficiency via complexation or ion exchange interactions. Another crucial factor that needed to be taken into account was the physical makeup of the materials. Major variations in sorption characteristics were found in the sorption kinetics, which were contingent on the cross-linking density, polymer solubility and polymeric architecture. An anion-exchange and complexing property-rich novel granular sorbent was created by the chemical reaction of a cross-linked copolymer of acrylonitrile with hexahydro-1,3,5-triacrylyltriazine when subjected to hydroxylamine. Modern techniques have been used to examine the physico-chemical characteristics of the final sorbent and demonstrate the characteristics of its structural morphology.
