“…Of note, chitosan has shown antitumor, antiulcer, immunostimulatory, antidiabetic, antioxidant and antibacterial activities [ 40 ]. Recently, chitosan and its derivatives have also received attention as adsorbents for heavy metal ions and their removal from wastewater [ 41 , 42 , 43 ]. Nanoparticles represent an excellent platform for a broad range of biological and biomedical applications.…”

Schiff bases (SBs) have extensive applications in different fields such as analytical, inorganic and organic chemistry. They are used as dyes, catalysts, polymer stabilizers, luminescence chemosensors, catalyzers in the fixation of CO2 biolubricant additives and have been suggested for solar energy applications as well. Further, a wide range of pharmacological and biological applications, such as antimalarial, antiproliferative, analgesic, anti-inflammatory, antiviral, antipyretic, antibacterial and antifungal uses, emphasize the need for SB synthesis. Several SBs conjugated with chitosan have been studied in order to enhance the antibacterial activity of chitosan. Moreover, the use of the nanoparticles of SBs may improve their antimicrobial effects. Herein, we provide an analytical overview of the antibacterial and antifungal properties of SBs and chitosan-based SBs as well as SBs-functionalized nanoparticles. The most relevant and recent literature was reviewed for this purpose.

“…However, no signi cant difference was observed in the chelation inhibition effect in the digestive tract compared with the traditional drug DTPA. Chitosan ingested through the digestive tract can be detected in the kidney in a short time [30,10,12]. In this study, the total radioactivity count in urine from the mPEGCS-DTPA group was signi cantly higher than that of the other two groups on the 1st and 2nd days after ingestion of 89 SrCl 2 .…”

“…However, the dosage form of DTPA or its structure can be modi ed to reduce its side effects, improve chelating ability, reduce dosage, increase usage, and extend its treatment time [8,9]. Chitosan (CS) has nontoxicity, biodegradability, good biocompatibility, and can be absorbed by organisms [10][11][12]. Furthermore, some experiments have shown that chitosan has radioprotective effects [13].…”

In this study, hydrophilic polymer polyethylene glycol monomethyl ether chitosan-diethylenetriamine pentaacetic acid (mPEGCS-DTPA) was synthesized via chemical synthesis and cross-linking, and its cytotoxicity and radiation protective effect in vivo were studied. The results revealed that mPEGCS-DTPA exhibits good cytocompatibility and increases the excretion of radionuclides through the digestiveand urinary tracts. The pathological results of the small intestine revealed that mPEGCS-DTPA exerts a good radiation-protective effect and could reduce the α and β-emitting radiation-induced damage of the intestinal mucosa. MPEGCS-DTPA can increase the excretion of radionuclides in the digestive tract and exhibits effective protection against radiation.

“…By changing sorbent and conditions, metal ions removal has been changed and confirmed that the adsorption process depended on the type, surface structure, and functional groups on the sorbent. [18,[65][66][67][68][69] In order to investigate the influence of different concentrations of Na(I), K(I), Ca(II), Mg(II) cations and Cl À and NO 3 À on the removal percentage of Pb(II) and Cd(II) ions using Gd/SrFe@SBCs many experiments were performed, [8,14,21,57,62] and the results are shown in Figure 13. Results demonstrate that the anions do not have much effect on the removal percentage of Pb(II) and Cd(II) ion, while in the presence of Ca(II) and Mg(II), the removal percentage of Pb(II) and Cd(II) ion shows higher decrease than Na(I) and K(I), because they have a higher positive charge and can easily interact to the negative charge of Gd/SrFe@SBCs.…”

In this work, novel Gd2O3/SrFe12O19@Schiff base chitosan (Gd/SrFe@SBCs) nanocomposite was prepared, and characterized using FT‐IR, XRD, DSC, VSM, FE‐SEM, X‐ray energy dispersive spectrum (EDS), and map analyses. All results confirm that the Gd2O3/SrFe12O19 nanocomposite/Schiff base chitosan was successfully prepared. EDS and map analyses predict that all elements are well distributed to the compound. VSM shows that the title compound has high saturation magnetic of 17.35 emu/g with high coercivity of 4,664 Oe. In addition, Gd/SrFe@SBCs were used as new adsorbents to the removal of Pb(II) and Cd(II) ions from aqueous solution, and results confirm that the removal efficiency of Pb(II) (98%) is higher than Cd(II) (78%) ion. At best conditions, the maximum adsorption capacity for Pb(II) is 183.7 and for Cd(II) is 146.2 mg/g. Reusability results show that the adsorption efficiency of Gd/SrFe@SBCs remained above 93% for Pb(II) and 71% for Cd(II) after five adsorption/desorption cycles. The effect of coexisting cation and anions was studied and confirm that the Gd/SrFe@SBCs had selective adsorption toward Pb(II). According to these results, we proposed that Gd/SrFe@SBCs studied as a sorbent to removal of other heavy metal ions.
