Facile fabrication of magnetic carboxymethyl starch/poly(vinyl alcohol) composite gel for methylene blue removal

Graphene Oxide Reinforced Alginate/PVA Double Network Hydrogels for Efficient Dye Removal

“…In recent years, hydrogels with 3D structures as adsorptive materials for the purpose of dye wastewater treatment have drawn widespread attention [7,8,9]. Dye molecules can permeate into 3D hydrogels with high adsorption rates, integrating with molecular chains of hydrogels by forming hydrogen bonding or electrostatic interactions; therefore, these dye molecules can be readily immobilized by the hydrogel chains.…”

Facile fabrication of a magnetic self-healing poly(vinyl alcohol) composite hydrogel

“…As a result, functional hydrogels are currently a hot research topic, and a large number of functional hydrogels have been developed, [6][7][8][9] such as ternary interpenetrating microvascular networks, 10 metallo-hydrogels, 11 and peptide based hydrogels. 12 Magnetic hydrogels are a type of promising functional hydrogel with magnetic properties and can be prepared by two main methods: 13,14 one is to blend pre-synthesized magnetic iron oxide nanoparticles (MIONs) with hydrogels in solution and to crosslink the MIONs with the polymer, the other is in situ generation of MIONs in the preparation of hydrogels. Magnetic hydrogels have been widely used in biological elds such as magnetic resonance imaging, 15 magnetically targeted hyperthermia, 16 drug delivery, 17,18 and immobilization of proteins, 19 which have intrinsic magnetic property and favorable biocompatibility.…”

Synthesis of porous starch xerogels modified with mercaptosuccinic acid to remove hazardous gardenia yellow

“…More importantly, natural polysaccharides contained abundant active functionalities such as hydroxyl, carboxyl and amino groups, which enabled their further modification for effective dyes removal [1,[21][22][23]. Starch was one of the natural polysaccharides functioning as an important energy source for humans.…”
