Synthesis of magnetic Fe3O4/graphene aerogel for the removal of 2,4-dichlorophenoxyacetic acid herbicide from water

“…[54][55][56] In the environment, metal oxide nanoparticles were combined with graphene as a framework to enhance their adsorption capabilities for sizes up to micrometers and thicknesses below a few nanometers. [57][58][59][60] Aerogels based on graphene are among the world's lightest materials. Because of their remarkable qualities, which include high mechanical strength, electrical conductivity, thermal resistance, and adsorption capacity, the academy and industry are becoming increasingly interested in them, consequently, research was done on the intriguing prospective uses of graphene aerogels in energy storage, energy conversion, and environmental preservation.…”

Catalytic activity of a new Cd (II) complex in the peroxidation of cyclohexane and the resulting CdO nanoparticles in the removal of Congo red

“…However, many physicochemical or chemical methods have been developed and used for wastewater treatment, such as ozonation, nanofiltration, coagulation/flocculation, and cloud point extraction 24–27 . Among these methods, adsorption is one of the most widely used methods to remove pollutants compared to other conventional methods 28–32 . Previously, Tadjarodi et al 33 prepared cauliflower‐like nanoparticles of CdO by mechanochemical technique and used them for the adsorption of CR.…”

“…[24][25][26][27] Among these methods, adsorption is one of the most widely used methods to remove pollutants compared to other conventional methods. [28][29][30][31][32] Previously, Tadjarodi et al 33 prepared cauliflower-like nanoparticles of CdO by mechanochemical technique and used them for the adsorption of CR. They reported that the maximum amount of CR removed at room temperature is 588.24 mg g À1 .…”
