Surface modified magnetic nanoparticles as efficient and green sorbents: Synthesis, characterization, and application for the removal of anionic dye

Environmental implications and applications of engineered nanoscale magnetite and its hybrid nanocomposites: A review of recent literature

“…Sunset yellow anionic dye is removed by aminopropyltriethoxysilane modified MNPs [240]. A Fe3O4/metal-organic frameworks (MOFs) composite adsorbs MB and methyl violet from an aqueous solution and the used Fe3O4/MOFs could be regenerated by acetonitrile [241].…”

A comparison investigation on photocatalytic activity performance and adsorption efficiency for the removal of cationic dye: Quantum dots vs. magnetic nanoparticles

“…The solution was heated to 85 C, under nitrogen atmosphere. Subsequently, the ammonium hydroxide solution (10 mL, 25%; w/w) was added drop-wise to the reaction mixture and was allowed to continue about 1 h. After the reaction, the obtained Fe 3 O 4 MNPs precipitate was separated from the reaction medium by a magnetic field, and washed four times with 100 mL of deionized water, to remove the impurities and unreacted materials [7].…”

“…Some of the methods for removal of pollutants from wastewater are adsorption [7] membrane separation [8], catalytic ozonation [9], Fenton [10], electro-Fenton [11], advanced oxidation process [12,13], electrochemical degradation [14], photocatalytic degradation [15][16][17] biodegradation [18], and ultrasonic irradiation [19]. These methods have their own advantages and disadvantages.…”

Selective Adsorption and Photocatalytic Degradation of Dyes Using Polyoxometalate Hybrid Supported on Magnetic Activated Carbon Nanoparticles under Sunlight, Visible, and UV Irradiation

“…Consequently, treatment of dye-contaminated wastewaters with decontamination processes is necessary before their discharge. Adsorption of dyes on inexpensive and efficient solid supports especially on activated carbon (AC) and AC composites is one of the simplest and most economical methods for removing dyes from wastewater [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]; however, the disposal of residues is still a problem. Advanced oxidation processes (AOPs) are widely accepted as an efficient method for dye-contaminated wastewater due to complete degradation of organics into carbon dioxide and water.…”
