Arabinoxylan was obtained from alkaline extraction of corn fiber (with an aqueous solution of 0.25 M of sodium hydroxide, under stirring at 30 °C for 7 h), and the extract was purified in a hollow-fiber membrane unit (UFP-100-C-5A, from GE Healthcare, Chicago, IL, USA), according to the procedure used by Serra et al., 2020 [15 (link)]. The purified extract was freeze-dried, and the solid was stored in a sealed plastic bag at −20 °C. Activated charcoal (Sigma-Aldrich, St. Louis, MO, USA) and hydrogen peroxide (José Manuel Gomes dos Santos LDA, Odivelas, Portugal) were used for the decolorization process. For the formulation of films, glycerol (Sigma-Aldrich, USA) and citric acid (PanReac, Barcelona, Spain) were used. For antioxidant activity determination, sodium acetate (Riedel-de-Haën, Seelze, Germany), acetic acid glacial (Fisher Chemical, Loughborough, UK), TPTZ (2,3,5-triphenyltetrazolium chloride) (Sigma-Aldrich, USA), HCl (Honeywell, Wien, Austria), and ferric chloride (PanReac, Spain) were used.
Sodium acetate
Manufactured by Honeywell
Sourced in Germany
Sodium acetate is a salt compound commonly used in laboratory settings. It functions as a buffer solution, helping to maintain a stable pH level in various chemical reactions and processes.

All reagents were of analytical grade and were used without further purification. Multiwalled carbon nanotubes (MWCNT) with ~95% purity, 30 ± 10 nm diameter, and 1–5 µm length were from NanoLab, Waltham, MA, USA. 4-nitroaniline, salicylaldehyde, o-phenylenediamine, chitosan (Chit) of low molecular weight with a degree of deacetylation of 80%, ethanol, toluene, diethyl ether, and acetic acid were acquired from Sigma-Aldrich. Sodium nitrite, sodium acetate, and trisodium citrate were obtained from Merck. Acetate buffer solutions of various pH values were prepared by mixing standard stock solutions of 0.1 M sodium acetate and 0.1 M acetic acid and adjusting the pH with HCl or NaOH, both from Riedel De Haën, Germany. For the measurement of Hg (II), the appropriate amount of Hg(NO3)2 (Fisher Scientific, Waltham, MA, USA) was dissolved in water.
All solutions were prepared with Millipore MilliQ ultrapure water (resistivity > 18 MΩ cm) and experiments were performed at room temperature (25 ± 1 °C).

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.
