polyacrylamide granules/polyacrylamide granules in luxembourg
A novel polyacrylamide (PAM) / sodium alginate (SA) adsorbent with double network structure was prepared by emulsion polymerization of acrylamide (AM) and SA. The chemical structure, thermal stability, crystallinity, pore size and distribution, surface area, surface morphology and energy dispersive spectrum of PAM/SA microspheres were determined by FTIR, TGA, XRD, BET, SEM and EDS.
Polyacrylamide-grafted-sodium alginate copolymers were prepared by persulfate-induced radical polymerization by using polymer-to-monomer ratios of 2 : 1 and 1 : 1.
