“…While these composites can be produced with a variety of polymer types including polytetrafluoroethylene (PTFE), , butyl methacrylate- co -ethylene dimethacrylate (BMA-EDMA), and poly(methyl methacrylate) (PMMA); , the focus of the current paper is where the matrix phase is polyacrylonitrile (PAN). PAN has the chemical formula of (CH 2 CHCN) n (see Figure ), and the International Union of Pure and Applied Chemistry (IUPAC) name for PAN is poly(1-acrylonitrile), but PAN has other names including Creslan 61 and polyvinyl cyanide.…”

Polyacrylonitrile (PAN) is a synthetic polymer that shows high potential for use in a wide range of environmental remediation applications. PAN can be implemented in various ways within a batch or continuous process stream for use as a passive scaffold holding active gettering materials in place or where the PAN scaffold (e.g., beads, fiber mats, membranes) is functionalized with active chelating groups (e.g., amine, hydrazide, amidoximes, carboxyl). Application spaces covered in this review include remediation of heavy metals (e.g., Ag, As, Cd, Cr 6+ , Cu, Pb, Sb, and Se), high-dose fission products (e.g., 90 Sr, 137 Cs), radioiodine (i.e., 129 I), noble gases (i.e., Xe, 85 Kr), rare earths (e.g., Ce, Y), and actinides (e.g., Am, Pu, U). Methods for producing PAN composite sorbents are discussed. Options are also discussed for removing the PAN matrix following chemisorption of an active contaminant to minimize waste volumes requiring disposal.
