The contents of N, C, H, and O were measured by an elemental analyzer (Vraio EL, Elementar, Hanau, German), which were used to estimate the conversion rate of the cyanidation and amidoxime reaction. The X-ray photoelectron spectroscopy (XPS) (Bruker BioSpin GmbH, Karlsruhe, Germany) was used to record the samples and to detect elements such as C, O, N, and Th(IV) in the AO-CELL. The morphological features of the cellulose and its derivatives were examined by the scanning electron microscope (SEM, Hitachi S-4800, Tokyo, Japan) and energy dispersive spectrometer (X-Max 80, Oxford Instruments, Oxford, UK). A Fourier transform infrared spectroscopy (FT-IR) (Nicolet Avatar 360, Thermo Nicolet, Waltham, MA, USA) spectrum spectrometer was used to characterize the material functional group identifications in the range between 4000 and 500 cm−1 by mixing 0.01 g of the material with 0.1 g KBr (spectroscopy grade) pellets. The concentration of Th(IV) was determined by spectrophotometer method (Perkin-Elmer, Waltham, MA, USA) at a wavelength of 652 nm using Th(IV)–Arsenazo(III) complex [17 (link),54 (link)]. All the experimental data were the average of duplicate experiments, and the relative errors of data were less than 5%.

All compounds were fully characterized
by spectroscopic data. The NMR spectra were recorded on a Bruker DRX500
& DRX600. Chemical shifts (δ) are expressed in ppm, J values are given in Hz, and deuterated DMSO-d6 & CDCl3 were used as the solvent. IR
spectra were recorded on a FT-IR Thermo Nicolet Avatar 360 using a
KBr pellet. The reactions were monitored by thin layer chromatography
using silica gel GF254. The melting points were determined
on a XT-4A melting point apparatus and are uncorrected. HRMs were
performed on an Agilent LC/Msd TOF instrument.

Coating of MDP1 on hydrogel surface was confirmed by ATR-FTIR analysis. This assay determined the newly formed functional groups in MECs-MDP1 in comparison to MECs. The IR spectra of the MECs-MDP1 hydrogel were recorded at 400-4,000 cm-1 by a FTIR instrument (Thermo Nicolet Avatar 360, United States).
Scanning Electron Microscopy (SEM) was used to assess the morphology of synthesized hydrogels (MECs and MECs-MDP1) using a SEM instrument (AIS2100C-SERON Technology, South Korea). To perform this analysis, the hydrogel samples were fixed with 2.5% glutaraldehyde and freeze-dried to ensure complete drying. The samples were coated with nanogold particles prior to visualization.

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.
