Synthesis and characterization of diphenylamine grafted onto sodium alginate for metal removal

Preparation and evaluation of the antimicrobial activity of sodium alginate-grafted diphenylamine embedded with silver nanoparticles

“…6a). In addition to NaAlg peaks, a new peaks appeared related to DPA δ7.25 (t, J = 7.0 Hz, 4H), 7.07 (d, J = 7.7 Hz, 4 H), 6.92 (t, J = 7.3 Hz, 2H) which confirm the successful grafting of DPA onto NaAlg successfully [33].…”

“…AgNPs have piqued the interest of researchers due to their electronic properties, appealing optical properties, and excellent antimicrobial activities [29][30][31]. AgNPs have strong cytotoxicity for a wide range of microorganisms and are widely used as an antibacterial agent [32,33].…”

The preparation, characterization and catalytic activity of Ni NPs supported on porous alginate-g-poly(p-styrene sulfonamide-co-acrylamide)

“…The diffraction peaks appeared at 2q ¼ 60 and can be attributed to the Ni NPs. 37 Meanwhile, in the XRD pattern of the Alg-PSSA-co-ACA@Ni nanocomposite sample, an amorphous phase is observed, which is related to the presence of amorphous polymer laments of acrylamide (2q ¼ 20-30 degrees), 38 and sodium alginate (2q ¼ 35-40 degrees), 39 and polystyrene sulfonamide (2q ¼ 20-30 degrees). 40 It is worth noting that the crystal structure of the recovered catalyst sample is quite similar to that of the original catalyst structure and the peak positions of the peaks have only changed a little, indicating the stability of the recovered catalyst.…”

Insights into the Synergistic Removal of Copper(II), Cadmium(II), and Chromium(III) Ions Using Modified Chitosan Based on Schiff Bases-g-poly(acrylonitrile)

“…Many biosorptions like fungi, algae, seaweed, microorganisms, and several biopolymers were applied in the metal ion uptake from wastewater. Also, composite materials were applied in the removal of heavy metal ions from wastewater. − The polysaccharides are renewable elements that are presently being used heavily in water purification .…”

“…14 The uptake of heavy metal ions from aqueous solution media by adsorption is considered one of the highly efficacious methods used, related to its ease of uptake, low cost, ease, and high selectivity. 15−17 Many biosorptions like fungi, 18 algae, 19 seaweed, 20 microorganisms, 21 and several biopolymers 22 were applied in the metal ion uptake from wastewater. Also, composite materials were applied in the removal of heavy metal ions from wastewater.…”
