“…In the study it was investigated that Langmuir isotherm for the lead ions removal by using activated carbon produced from coconut shell showed the 24.4 mg/g adsorption capacity, followed by mercury and copper ions with adsorption capacity of 17.24 mg/g. Langmuir isotherm model provides a better correlation coefficient for lead and mercury ions while for copper ions correlation coefficient was low [40].…”

“…Park et alwerestudied the competitive adsorption of heavy metal ions onto sesame straw biochar in waste water solution. The maximum adsorption capacities (mg g -1 ) of metals by sesame straw biochar were in order of lead ion (102) > cadmium ion (86) > chromium ion (65) > copper ion (55) > zinc ion (34) in the monometal adsorption isotherm and the multimetal adsorption isotherm were in order of lead ion (88) > copper ion (40) > chromium ion (21) > zinc ion (7) ≥ cadmium ion (5). It was observed that cadmium ion was easily exchanged and substituted by other metals [58].…”

Manuscript discussed the role of different parameters for the metal ions removal from industrial waste water. The metal ions removal from waste water is essential to decrease the diseases and environmental hazards caused by heavy metal ions. The different parameters of adsorption including the effect of contact time, dose, pH, temperature, kinetics and Brunauer-Emmett-Teller analysis is discussed. This manuscript focuses on biosorption of metal ions, competitive adsorption of metal ions and ligand based adsorption of metal ions. This manuscript also focuses on the commercially available adsorbent used in the removal of metal ions efficiently including polymeric adsorbent and activated carbon.

“…77 On the other hand, alternative adsorbents such as fly ash, graphene, clay, carbon nanotubes and polysaccharides were reported for removal of MB. [80][81][82][83][84][85][86][87] Among these adsorbents, Mittal et al 80 reported that using polysaccharides-based adsorbents is a promising strategy for MB dye removal from aqueous solutions. This is due to their enhanced adsorption capacity amongst other attractive properties.…”

Water pollution by organic dyes continues to pose a serious health and environmental threat to the ecosystem. Although adsorption using biopolymer-based hydrogels has proven to be an ideal technique for the treatment of these dye contaminants from aqueous solutions, these hydrogels suffer from lack of mechanical stability and recovery as compared to synthetic polymers. Herein, we review the low-cost synthesis of hydrogel incorporated with inorganic components mainly focusing on strategies to improve the mechanical stability and separation of the hydrogel in removing methylene blue (MB) dye from aqueous solution. The literature shows that hydrogel nanocomposites are a class of materials that have flourished significant consideration, especially concerning water treatment. In adsorption technology, hydrogel nanocomposites act as absorbents, prominent to enhance their removal efficiency towards contaminants. This review highlights the preparation and use of hydrogel nanocomposites as efficient adsorbents. In-depth discussions on adsorption and diverse synthetic routes of hydrogels have been devoted to applications of these nanocomposites and are compared in this contribution to the removal efficiency of MB dye from wastewater.

“…At present, the research idea is basically to change the micro-nano adsorbent into a large volume adsorbent, which is called immobilization method. For example, the adsorbent is loaded on the framework by coating, deposition, grafting, in-situ synthesis and other ways ( Ahmed and Jhung, 2014 ; Jethave, et al, 2018 ; Moreno-López, et al, 2019 ; Tahmasebi, et al, 2019 ; Wang, et al, 2019 ; Zhou, et al, 2019 ; Wang, et al, 2021 ). It is also a common immobilization method to make the adsorbent into a monolith using a binder ( Salem and Akbari Sene, 2011 ; Novais, et al, 2016 ; Xiang, et al, 2017 ), which is similar to the method of melt blending adsorbent/polymer ( Dlamini, et al, 2011 ; Makhetha, et al, 2016 ; Moja, et al, 2020 ).…”

3D printed cylindrical capsules as a Chlorella pyrenoidosa immobilization device for removal of lead ions contamination

et al. 2022

Immobilization is considered as a promising strategy toward the practical applications of powdered adsorbent. Herein, three dimensional (3D) printing cylindrical capsules with cross-linked PVA hydrogels membrane in encapsulate Chlorella pyrenoidosa (Cp) were utilized for removal of lead ions. The chemical compositions, hydrogels performance and morphologies of the membranes were determined by Fourier transformed infrared spectroscopy (FTIR), cross-linking degree, swelling degree, membrane flux and scanning electron microscopy (SEM). It is found that PVA cross-linking structure is successfully synthesized on the surface of capsule body and cap due to the presence of PVA in the filament. The lead ions adsorption capacity related to initial concentration of 50 mg/L in 48 h is reached 75.61%, revealing a good removal ability. The self-floating 3D printed capsules device also shows an excellent recovering property. After 7 runs of adsorption experiment, the lead ions adsorption ratio remains 78.56%, which will bring a broad prospect in wastewater treatment, chemical slow release along with sample preparation and separation.
