Synthesis of dual-responsive
superparamagnetic hydrogel nanocomposites, AA-VSA-P/SPIONs, with different
concentration of SPIONs (Fe₃O₄) was conducted
using acrylic acid (AA) (Sigma-Aldrich), vinylsulfonic acid (VSA)
(Sigma-Aldrich) monomers, benzoyl peroxide (BPO) (Himedia) initiator,
and ethylene glycol dimethacrylate (EGDMA) (Alfa Aesar) cross-linker
along with synthesized SPIONs. To synthesize SPIONs, iron(II) chloride
tetrahydrate (FeCl₂·4H₂O) (Sigma-Aldrich)
and iron(III) chloride hexahydrate (FeCl₃·6H₂O) (Sigma-Aldrich) were used. The study on dye adsorption properties
of the superparamagnetic hydrogels, AA-VSA-P/SPIONs, was carried out
using methylene blue (MB) dye (Sigma-Aldrich). The required aqueous
solutions were prepared with deionized water, whereas the pH of aqueous
solutions was maintained by adding suitable amounts of HCl (0.05 M)
or NaOH (0.05 M) solutions (Merck).

The poly(acrylic acid-co-vinylsulfonic acid) magnetic hydrogel was prepared using
acrylic acid (AA) (Sigma-Aldrich) and vinylsulfonic acid (VSA) (Sigma-Aldrich)
as monomers, along with benzoyl peroxide (BPO) (HiMedia) and ethylene
glycol dimethacrylate (EGDMA) (Alfa Aesar) as an initiator and a cross-linker,
respectively. For Fe₃O₄ nanoparticle synthesis,
iron(II) chloride tetrahydrate (FeCl₂·4H₂O) (Sigma-Aldrich) and iron(III) chloride (FeCl₃·6H₂O) (Sigma-Aldrich) were used. The required aqueous solutions
were prepared with deionized water, and the pH of aqueous solutions
was maintained by adding appropriate amounts of HCl (0.05 M) or NaOH
(0.05 M) solutions (Merck).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
