Abstract

Radiation-induced graft polymerization is a powerful tool for the following reasons: (1) From the macroscopic standpoint, the form of the adsorbent can be selected. For example, nonwoven fabrics and porous sheets may be adopted as trunk polymers instead of beads or granules. (2) From the microscopic standpoint, graft chains are relatively flexible, providing a novel space for ions and molecules. For example, proteins can be multilayered via multipoint binding, and inorganic precipitates can be immobilized through entanglement and penetration. (3) From an industrial standpoint, the pre-irradiation method is advantageous in that the processes, i.e., irradiation and grafting, are separable. An electron-beam-irradiated wound film and bobbins of gamma-ray-irradiated fibers can be used as trunk polymers in continuous and batch modes, respectively. Many polymeric adsorbents of various forms and components can be produced by radiation-induced graft polymerization.
