Synthesis and Application of Bacterial Cellulose‐co‐(poly)acrylamide as an Adsorbent for Cu and Pb Metal Ions

Abstract

The bacterial cellulose‐co‐polyacrylamide (BC‐PAAM) is successfully synthesized by radiation‐induced graft polymerization using gamma rays with the simultaneous technique. The optimum irradiation dose applied is 50 kGy and the mass ratio among acrylamide (AAm) and bacterial cellulose (BC) is 1:4. The sorption of aqueous Cu and Pb onto BC‐PAAM is investigated in the relation of pH 3 and 5. The heavy metal ions are applied as single during adsorption study. The sorption uptake of the metal ions by BC‐PAAM shows that the adsorption capacity is higher at pH of 5 compared to the adsorption capacity of pH 3, both for Cu and Pb metal ions. The adsorption capacity obtained in the condition of pH 5 is 20.88 and 81.79 mg g−1 for Cu and Pb, respectively. While the adsorption efficiency in pH 5 is 29.54% (for Cu) and 92.76% (for Pb). The adsorbent (before and after metal ions uptake) is characterized by Fourier transform infrared spectroscopy and differential scanning calorimetry.

Pb(II) Adsorption Properties of a Three-Dimensional Porous Bacterial Cellulose/Graphene Oxide Composite Hydrogel Subjected to Ultrasonic Treatment

“…Compared w the spectrum of BC, two new peaks appear at 167.82 ppm and 172.12 ppm, attributed carboxyl group and an ester group, respectively [34]. The carboxyl group stems from unreacted group on GO, and the ester group is produced from the reaction of GO with The results of this analysis are in accordance with those of the FT-IR pattern analysis, wh infers that the species of oxygenic groups of BC/GO-1 are more abundant compared to The 13 C-NMR spectrum is sensitive to crystalline and amorphous regions and can used to analyze the crystallinity of bacterial cellulose. In the 13 C-NMR spectrum,…”

“…The morphology evolution was observed using a NOVA NANOSEM 430-field emission scanning electron microscope (from FEI USA, Inc., Hillsboro, OR, USA) at an acceleration voltage of 15 kV with a beam of 3.0 and a JEM-2100F transmission electron microscope (from Nippon Electronics Co., Tokyo, Japan). The chemical structure was analyzed via 13 C-NMR spectroscopy, observed with an AVANCE digital 400. The surface Zeta potential of BC/GO-1 was determined using a Zeta sizer nanoparticle size potentiometer (Nano-ZS90), Malvern, UK.…”

“…Bacterial cellulose (BC), a biosynthesized cellulose, is a prospective biosorbent for Pb(II) elimination owing to its three-dimensional cross-linked network structure, relatively large surface area, and rich hydroxyl groups in its chain [12][13][14]. The adsorption performance of BC mainly depends on the hydroxyl activity of O( 2 structure [15].…”

Nanopolymer: Overview, Innovation and Applications

“…Saragih et al [46] studies, cellulose nanofiber has been isolated using the steam explosion method from lignin and hemicellulose of pseudostem of abaca (Musa textilis). Oktaviani et al [47] synthesized the bacterial cellulose-co-polyacrylamide by radiation-induced graft polymerization using gamma rays with the simultaneous technique. Nano biopolymers and nanomaterials such as SFNPs, SFNCs, POSS, ZCPs, and nickel hydroxide nanosheet have shown their roles in NFtransport.…”
