“…On a closer look at Table 7, both Godiya et al 29 and Huang et al 32 reported higher amount of adsorption of Cd(II) compared to our work. Similarly, Jia et al 22 reported a higher amount of adsorption of Ni(II) compared to our work. All three of them used the lowermolecular-weight-based repeat units such as acrylamide, acrylic acid, and methyl acrylate, respectively, which provide more number of binding sites than the same weight of polysaccharide-based hydrogels.…”

“…Adsorption behavior depends on various parameters such as ionic concentration, pH, contact time, temperature, etc. In recent years, acrylate-, acrylamide-, alginate-, poly(vinyl alcohol)-, and chitosan-based hydrogels are used to remove Ni(II) and Cd(II) from wastewater. Cellulose-based hydrogels are widely used for wastewater treatment .…”

Carboxymethyl cellulose (CMC), microcrystalline cellulose (MCC), and xylan are cross-linked with β-cyclodextrin (βCD) using ethylene glycol diglycidyl ether cross-linker to produce hydrogels, namely, βCD-CMC, βCD-MCC, and βCD-xylan, in alkaline medium at 1:1 mole ratio. Additionally pure βCD gel is also prepared in alkaline medium. The synthesized hydrogels are characterized by Fourier transform infrared spectroscopy, and the swelling ratio, gel fraction, and the morphologies are observed by a microscope. The hydrogels are used to adsorb cadmium (Cd(II)) and nickel (Ni(II)) ions from aqueous solution. The adsorption studies are carried out by varying adsorbent dosage from 80 to 500 mg, concentration from 5 to 500 mg L–1, pH from 2 to 8, and temperature from 25 to 55 °C. The equilibrium adsorption data closely follow the Langmuir model, suggesting the monolayer adsorption of metal ions by the hydrogels. The adsorption kinetics are found to closely follow the pseudo-second-order model.

“…On the other hand, the negative value of Δ S ° suggests that decreased randomness at the solid–liquid interface during adsorption of Fe 3+ ions onto CMC‐g‐AMPS hydrogel. The result is similar to previous studies . In addition, the negative value of Δ S ° also reflects the poor affinity of Fe 3+ ion towards CMC‐g‐AMPS hydrogel .…”

BACKGROUND An alternative carboxymethyl cellulose‐based biosorbent hydrogel was synthesized by grafting 2‐acrylamido‐2‐methylpropanesulfonic acid (AMPS) onto the prepared carboxymethyl cellulose backbone via microwave heating. Response surface methodology was employed to optimize the hydrogel synthesis condition for maximum gel content with respect to AMPS dose, N,N′‐methylene‐bis‐acrylamide dose, and microwave exposure time. The prepared gels were then characterized and evaluated in terms of their heavy metal ions adsorption performance and reusability. RESULTS The optimum synthesis condition yielded the maximum gel content and maximum equilibrium swelling of 96.33% and 2819 ± 15%, respectively. The Langmuir model fitted the experimental isotherm data well, with maximum adsorption capacity of 86.21, 102.04 and 33.56 mg g‐1 for Cu2+, Pb2+ and Fe3+, respectively. Microwave heating was clearly noted to result in hydrogel of higher porosity and could shorten the synthesis time by 88.33%; the gel content was 7.46% higher compared with that obtained via conventional heating. CONCLUSION Microwave‐assisted heating is a feasible alternative and an efficient technique for CMC‐g‐AMPS hydrogel synthesis. The optimized CMC‐g‐AMPS hydrogel exhibited good performance for Cu2+, Pb2+ and Fe3+ ions removal and was satisfactorily reused, thus contributing to the alleviation of environmental problems caused by discarded rice straw and water contaminated with heavy metal ions. © 2017 Society of Chemical Industry

Novel cross-flow disturbance of ceramic membrane was used for the first time to enhance the adsorption of highly toxic Cu(II) onto Zr-based metal−organic frameworks (Zr-MOFs). Effects of temperature and pH were investigated on the adsorption process of Cu(II) onto the MOFs using the jar test. The results showed that the MOFs can well adsorb Cu(II) (59.8 mg g −1 ) at a pH of 6 and a temperature of 40 °C. On the basis of this, the MOFs were then added into a novel cross-flow ceramic membrane filtration system. Effects of the operation temperature and membrane pore size were also investigated on the adsorption process. The results showed that Zr-MOFs adsorption of Cu(II) increased with temperature. The ceramic membrane with a pore size of 200 nm exhibited better Cu(II) removal and membrane flux than did the 50 nm membrane, as well as better kinetic data fit of the pseudo-secondorder model. With the aid of cross-flow disturbance of ceramic membrane, the capacity was incredibly increased to 988.2 mg g −1 at a pH of 6, temperature of 40 °C, cross-flow velocity of 4.5 m s −1 , and trans-membrane pressure of 0.05 MPa. The principal advantages of this method are a significant enhancement of adsorption onto the Zr-MOFs in the removal of Cu(II) and convenient application in the continuous treatment of heavy metal wastewater. This can be used as an effective method in continuous adsorptive removal of heavy metals from wastewater.
