Optimization of carboxylated graphene oxide (C-GO) content in polymer matrix: Synthesis, characterization, and application study

One-Pot Synthesis of Carboxyl-Functionalized Hyper-Cross-Linked Microporous Polymer Based on the Dual-Purpose Reagent Strategy for the Efficient Removal of Methylene Blue from Water

“…2−4 Among these technologies, adsorption is one of the most preferred ones for eliminating organic dyes from wastewaters, as it does not use any toxic substances and is cost-effective, easy to operate, highly efficient, and recyclable. 5−10 Recent interdisciplinary work in the fields of environmental remediation and functional materials has led to the development of adsorbents for the removal of MB dye, such as cellulose microsphere, 9 hydrogel, 11 graphene, 12 carbon nanotubes, 13 and metal (covalent) organic frameworks (MOFs/COFs). 14,15 Of the wide selection of MB adsorbents, carboxyl-functionalized porous materials provide excellent extraction capability, because, in addition to hydrophobic, hydrogen bond, and π−π stacking, the electrostatic mechanism is also involved in the relationship between the anionic moieties and cationic MB.…”

“…However, in recent years, MB has attracted significant attention due to its risks to human health, which include high blood pressure, gastrointestinal pain, headache, and fever . To minimize human exposure to MB, several technologies based on physical, chemical, and biological approaches have been developed and implemented to remove dye contaminants from wastewater, including advanced oxidation techniques, biodegradation, photodegradation, and adsorption. − Among these technologies, adsorption is one of the most preferred ones for eliminating organic dyes from wastewaters, as it does not use any toxic substances and is cost-effective, easy to operate, highly efficient, and recyclable. − Recent interdisciplinary work in the fields of environmental remediation and functional materials has led to the development of adsorbents for the removal of MB dye, such as cellulose microsphere, hydrogel, graphene, carbon nanotubes, and metal (covalent) organic frameworks (MOFs/COFs). , Of the wide selection of MB adsorbents, carboxyl-functionalized porous materials provide excellent extraction capability, because, in addition to hydrophobic, hydrogen bond, and π–π stacking, the electrostatic mechanism is also involved in the relationship between the anionic moieties and cationic MB. ,− …”
