Reduced graphene oxide decorated superporous polyacrylamide based interpenetrating network hydrogel as dye adsorbent

Interpenetrating polymer networks for desalination and water remediation: a comprehensive review of research trends and prospects

“…The removal efficiency of anionic MO dye was retained at 94.45% even aer similar cycles of repeated operation. 106 A stimuli-responsive, more specically pH-responsive superabsorbent based on PVA, PAA, and yeast was fabricated by Feng et al and the fabrication was realized using solution polymerization technique. From the measurements of mechanical integrity, it was concluded that the adsorbents could easily resist up to 5000 rpm of shear ow, and withstand 3 kg of load pressure.…”

Construction of adsorbents with graphene and its derivatives for wastewater treatment: a review

“…The adsorption equilibrium could be reached within 5 min, which is much shorter than the latter (75 h). 79 Due to their super-porous structure, large specific surface area, interpenetrating polymer network, hydrophilic voids with various functionalities (e.g., hydroxyl, amine, carboxyl, and sulfonic acid), and excellent mass transport ability, natural and synthetic polymer hydrogels have been intensively reported to immobilize graphene and derivatives to prepare polymer-based composite hydrogel adsorbents, such as alginate, 80 PAM, 81 sodium alginate grafted PAM, 82 poly(N-vinylimidazole-co-acrylic acid), 83 polyaniline, 84 and others. 85 Typically, our group fabricated PAM-based hydrogels filled with rGO sheets.…”

“…87 From the literature review, it can be concluded that a larger quantities of studies are devoted to cationic pollutant removal relative to that of anionic ones. Typically, cationic organic dye MB is regarded as one of the most frequently investigated adsorbates among other cationic dyes, including Rhodamine B (RhB), 81 malachite green (MG), 98 methylene green, 63 and methyl violet, 122 as shown in Tables 1 and 2. For inorganic adsorbates, cationic metal ions such as Cu 2+ , 47,59,123 Pb 2+ , 59,92 Hg 2+ , 124 Mn 2+ , 125 Cd 2+ , 93 Co 2+ , 59,74 Ni 2+ , 59,74 Zn 2+ , 59 and a series of rare-earth ions 126 are also widely employed and handled with various graphene-based adsorbents.…”

A Novel P@SiO2 Nano-Composite as Effective Adsorbent to Remove Methylene Blue Dye from Aqueous Media

“…Discharging dyes in the aquatic sphere, even at low concentrations, will harm all living organisms that live in water, animals, and humans, where it is a toxic, carcinogenic, mutagenic, and non-degradable materials that can stay in the environment for a long time [ 1 ]. Methylene blue (MB) dye is the most famous water contaminant that badly impacts health through abdominal disorders, respiratory distress, skin sensitization, and blindness [ 2 , 3 , 4 ]. Also, methylene blue, with its deep blue color, reduces the penetration of the light for aquatic organisms, which has a bad effect on the environment and disorders the balance of the ecosystem leading to dangerous issues for all forms of living systems and thus threatens their life [ 1 , 5 , 6 , 7 ].…”
