“…The introduction of quaternary ammonium groups significantly changed the physicochemical properties of chitosan macromolecules. 31,32 The 13 CNMR spectrum of N-CCTS also showed that the grafting reaction mainly occurred on the primary hydroxyl group on the C6 atom in the chitosan macromolecule.…”

In this work, n-alkyl chitosan (N-CTS) was obtained by alkylation modification of chitosan with n-butylaldehyde using Schiff alkali method. The etherifying agent 3-chloro-2-hydroxypropyl triethylammonium chloride (CHPTAC-ethyl) was synthesized from triethylamine and epichlorohydrin. The N-CTS and CHPTAC-ethyl were etherized to finally synthesize n-alkyl quaternary ammonium chitosan (N-CCTS). Scanning electron microscope, X-ray diffractometer, Fourier transform infrared, X-ray photoelectron spectroscopy, and 13 CNMR were used to characterize the surface morphology and chemical structure. Viscosity method and spectrophotometry were used to determine its physical and chemical properties. The etherification reaction mechanism was studied systematically and the influence of reaction conditions on the degree of substitution and solubility of N-CCTS was investigated. The minimum inhibitory concentration (MIC) of N-CCTS against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) was both 0.15 g/L, which was superior to the MIC value of natural chitosan. N-CCTS was used to finish rabbit hair fabric with citric acid as cross-linking agent and sodium hypophosphite as catalyst. The antibacterial and washing resistance of the product were investigated. After 25 times of washing, the antibacterial rate of N-CCTS against E. coli and S. aureus remained stable at about 90%, and the antibacterial rate was higher than that of N-CTS and natural chitosan, and it was a kind of natural polymer longacting antibacterial finishing agent for rabbit hair fabric.

“…Ion exchange and adsorption resin is a type of functional polymer material with network structure. It is widely used in light industry [1,2], food [3,4], medicine [5,6], environmental protection [7,8], and hydrometallurgy [9][10][11]. Chelating resin, as a special ion exchange resin having chelating functional groups, has the advantage of high selection during adsorption process and easy regeneration during desorption process [10].…”

Using polyacrylic resin followed by the substitution reaction with 6-aminohexyl hydroxamic acid, poly(6-acryloylamino-hexyl hydroxamic acid) resin (PAMHA) was successfully synthesized. PAMHA, a spherical resin with the particle size of 0.4 mm, is a novel polyamide hydroxamic acid chelating resin containing acylamino and hydroxamic acid functional groups. A series of influences (pH, contact time, temperature, and the initial concentrations of rare earth ions) were investigated to determine the adsorption properties. The adsorption capacity for La(III), Ce(III), and Y(III) ions were 1.030, 0.962, and 1.450 mmol·g−1, respectively. Thermodynamic and kinetic studies were also carried out to show that the uptake of rare earth ions onto PAMHA fitted well the pseudo-second-order model and Langmuir isotherm, and the adsorption process was spontaneous endothermic. In addition, desorption of rare earth ions was achieved by using 2 mol·L−1 HNO3 and desorption efficiencies for La(III), Ce(III), and Y(III) ions were 98.4, 99.1, and 98.8%, respectively. Properties of PAMHA resin were characterized by scanning electron microscope (SEM), Fourier transform infrared spectrometry (FTIR), and X-ray photoelectron spectrometer (XPS). The results showed that there was coordination between the rare earth ions with PAMHA and rare metal ions were chemically adsorbed on the surface of the PAMHA.

“…The resin functional groups adsorb heavy metal ions in water by ion exchange, showing good stability and recyclability. 14,15 The commercial cation exchange resin Amberlite IRC-86 was used for the recovery of Cu( ii ) from bioleaching wastewater, 16 and the recovery rate reached 78.9%. Although ion exchange resins are convenient for commercial applications and are of low cost for heavy metal ion wastewater treatment, the macroscopic size of the resins still limits the adsorption capacity of pollutants.…”
