“…Moreover, the spectrum of AMPSA presents some characteristic peaks: at 3236 cm −1 and corresponding to N-H [ 32 ] stretching vibrations of the amide group, at 3101, 3035, and 1611 cm −1 attributed to H-C=C stretching vibrations of the vinyl group [ 33 , 34 , 35 ] at 1232 and 1076 cm −1 characteristic for the asymmetric and symmetric stretching vibrations of the O=S=O group and additionally at 623 cm −1 assigned to stretching vibrations of the C-S group [ 36 ]. In PS1–PS4, the broad bands in the wavelength range 3600–3100 cm −1 result from the overlapping of the N-H and O-H stretching vibrations [ 37 , 38 ]. Two peaks appeared at positions 2985 and 2938 cm −1 and may be attributed to the aliphatic C-H stretching vibrations [ 39 ].…”

Thermosensitive polymers PS1–PS5 were synthesized via the surfactant free precipitation polymerization (SFPP) using 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPSA), and potassium persulfate (KPS) at 70 °C in aqueous environment. The effect of KPS concentrations on particle size and lower critical temperature solution (LCST) was examined by dynamic light scattering (DLS). The conductivity in the course of the synthesis and during cooling were investigated. The structural studies were performed by attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR), H nuclear magnetic resonance (1H NMR), thermogravimetric analysis (TGA/DTA) and powder X-ray diffraction (PXRD). ATR-FTIR, 1H NMR and PXRD data confirmed the polymeric nature of the material. TGA/DTA curves demonstrated thermal stability up to approx. 160 °C. The effect of temperature on the hydrodynamic diameter (HD) and zeta potential (ZP) were evaluated by dynamic light scattering (DLS) and electrophoretic mobility (EM) in 18–45 °C range. The LCST values were between 30 and 34 °C. HD and polydispersity index (PDI) of aqueous dispersions of the synthesized polymers PS1–PS5 at 18 °C were found to be 226 ± 35 nm (PDI = 0.42 ± 0.04), 299 ± 145 nm (PDI = 0.49 ± 0.29), 389 ± 39 nm (PDI = 0.28 ± 0.07), 584 ± 75 nm (PDI = 0.44 ± 0.06), and 271 ± 50.00 nm (PDI = 0.26 ± 0.14), respectively. At 18 °C the ZPs of synthesized polymers suspensions were −13.14 ± 2.85 mV, −19.52 ± 2.86 mV, −7.73 ± 2.76 mV, −7.99 ± 1.70 mV, and −9.05 ± 2.60 mV for PS1–PS5, respectively. We found that the initiator concentration influences the physicochemical properties of products including the size of polymeric particles and the LCST.

“…There is a mass loss of less than 7% at 180 • C. Mass losses were approximately 20, 39 and 68% at 250, 300 and 350 • C, respectively. It was reported that the degradation because of decomposition of the -SO 3 H groups can be seen between 250-300 • C [7,13]. The mass loss from room temperature to 200 • C is due to VP content [4].…”

In this study, poly(2-acrylamido-2-methyl-1-propane sulfonic acid-co-1-vinyl-2-pyrrolidone), P(AMPS-co-VP), hydrogels were prepared by free radical cross-linking polymerization method in deionized water at 60 • C for 24 hours with different molar percentages of AMPS and VP. In the preparation of hydrogels, ammonium persulphate (APS), N,N'-methylenebisacrylamide (NMBA) and N,N,N',N'-tetramethylethylenediamine (TEMED) were used as initiator, cross-linking agent and accelerator, respectively. NMBA was used in amounts of 5, 6 and 8% with respect to total monomer concentration in the feed. The equilibrium swelling value (ESV) of P(AMPS-co-VP) hydrogels was determined in deionized water and in buffers with different pH values. ESV of P(AMPS-co-VP) hydrogels prepared with 5% NMBA is higher than that of the counterparts with 6 and 8%. Swelling behavior of hydrogels was strongly dependent on AMPS content and ESV decreased with increase in AMPS amount. An evident pHsensitivity was not observed for the P(AMPS-co-VP) hydrogels. The characterization study was performed using Fourier transform infrared spectroscopy and thermogravimetric analysis.

“…The removal of heavy metals from water and wastewater is essential because of the numerous adverse effects on human health and the environment [ 1 , 4 , 5 , 6 , 7 ]. Several methods are available such as chemical precipitation [ 8 ], coagulation/flocculation [ 9 ], membrane filtration [ 10 ], ion-exchange [ 11 ], bioremediation [ 12 ] and adsorption [ 13 ].…”

Removal of Cd2+ from Water by Use of Super-Macroporous Cryogels and Comparison to Commercial Adsorbents

et al. 2020

In this study amphoteric cryogels were synthesized by the use of free-radical co-polymerization of acrylate-based precursors (methacrylic acid and 2-acrylamido-2-methyl-1-propansulfonic acid) with allylamine at different ratios. The physico-chemical characteristics of the cryogels were examined using SEM/EDX, FT-IR, XPS and zeta potential measurements. The cryogels were tested toward Cd2+ removal from aqueous solutions at various pH and initial concentrations. Equilibrium studies revealed a maximum sorption capacity in the range of 132–249 mg/g. Leaching experiments indicated the stability of Cd2+ in the cryogel structure. Based on kinetics, equilibrium and characterization results, possible removal mechanisms are proposed, indicating a combination of ion exchange and complexation of Cd2+ with the cryogels’ surface functional groups. The cryogels were compared to commercially available adsorbents (zeolite Y and cation exchange resin) for the removal of Cd2+ from various water matrices (ultrapure water, tap water and river water) and the results showed that, under the experimental conditions used, the cryogels can be more effective adsorbents.
