Sodium carboxymethyl cellulose,
polyacrylic acid, and hydrophilic carbon have been used to
improve the transport of NZVI in soil [14]. In order to enhance
the stability in the air, NZVI was supported on PolyFlo resin [15].
Recently, NZVI particles were effectively entrapped in calcium alginate
beads without significant reduction in their reactivity [16].
Entrapment of NZVI in porous beads will be a promising technology
in the application of NZVI particles. This study presents work
to entrap NZVI in a porous polymer
