Özet
In this study, a magnetic nano-sorbent (M-TACA) was linked with an N-methyl-d-glucamine (NMDG) picky functional group
using click chemistry, which is rapid, multifunctional, easy to use, and produces a large amount of product that is selective
to the target site. M-TACA were detected using scanning electron microscopy (SEM) and vibrating-sample magnetometry
(VSM) techniques. The efects of pH, contact time, initial Cr(VI) ion concentration, and M-TACA dosage on the sorption
process were examined. The sorption capacity of Cr(VI) ions to M-TACA nanoparticles difers depending on pH. The maximum sorption capacity of Cr(VI) ions to M-TACA nanoparticles was determined to be 117.65 mg/g at pH 3. The efects of
cationic ions Cu2+, Zn2+, and Ni2+ and anionic ions Cl−, PO4
3−, and SO4
2− on the removal of Cr(VI) were also investigated.
Sorption is more compatible with the Langmuir isotherm model than any other applied isotherm model. The Langmuir
isotherm model for sorption was shown to be more compatible than the other models among the isotherm model research.
Intra-particle difusion model was applied for the Cr(VI) ions sorption mechanism. Both surface and intra-particle sorption are
clearly diferent from one another in the two sorption stages. According to the M-TACA-Cr(VI) sorption systems computed
thermodynamic characteristics, the process was exothermic, spontaneous, and mixed physicochemical in nature. Moreover,
in reusability studies, M-TACA nano-sorbent was found to retain 96.8% sorption capacity after fve consecutive repetitions.
