Ultrasound-assisted synthesis of polyacrylamide-grafted sodium alginate and its application in dye removal

Description
Abstract
A polymeric adsorbent based on sodium alginate (SAG) grafted with polyacrylamide (PAM) (SAG- g-PAM) was synthesized using an ultrasound-assisted method. The addition polymerization was carried out with ammonium persulfate as the initiator, at different acrylamide (AM) concentrations. The SAG-g-PAM copolymers were evaluated by FTIR and 13C NMR spectroscopies, thermogravimetric analysis, grafting efficiency (%GE) and intrinsic viscosity in NaCl solution at 25 °C. Graft copolymers could be obtained in reaction lasting until 10 min by using ultrasound energy with grafting efficiency above 75%.

The decolorization efficiency and adsorption capacity of the SAG- g-PAM copolymers were investigated in the adsorption of methylene blue (MB). The dye adsorption was pH dependent, and adsorption capacity (69.13 mg/g) maxima was at pH 10. All the graft copolymers have shown the same decolorization efficiency (99%), and the best one for MB removing is the SAG-g-PAM6 (%GE = 75%), since lower acrylamide content is required in the synthesis.
