Synthesis of green nano iron particles (GnIP) and their application in adsorptive removal of As(III) and As(V) from aqueous solution

Sorption of cationic malachite green dye on phytogenic magnetic nanoparticles functionalized by 3-marcaptopropanic acid

“…Similarly, the reduction in M s values have also been reported by other researchers for green MNPs. 26,28,29,41,42 In addition, Fig. 8b demonstrates that the as-prepared 3-MPA@PMNPs can easily be separated from solution within a few seconds with the help of a permanent hand-held magnet.…”

“…1 In addition, most oen, green magnetic NPs have been used for the removal and recovery of heavy metal ions (Cr, Hg, Cd, As and Pd) from aqueous environments. [24][25][26][27][28][29][30] However, very limited information is available addressing the adsorptive performance of green MNPs to remove toxic dyes. 31,32 Despite this fact, different types of green MNPs (prepared by various types of plant extracts) have been utilized for the degradation of toxic dyes, but an adsorptive study is not yet reported.…”

Green Synthesis of Iron Nanoparticles and Their Environmental Applications and Implications

“…Prasad et al [80] studied the removal of arsenite(III) and arsenate(V) from aqueous solution using green synthesised iron nanoparticles. Mentha spicata L. synthesised iron nanoparticles showed absorption peaks at 360 and 430 nm confirmed by UV-Vis.…”

Synthesis, characterization, and reactivity of cellulose modified nano zero-valent iron for dye discoloration

“…Besides, other studies for increase of NZVI dispersity and mobility in water body or soil have been focused on coating iron nanoparticles with stabilizer via steric hindrance and electrostatic repulsion. These modifiers include various polymer electrolytes and surfactants, such as chitosan [36,37], xanthan gum [38], cetyltrimethyl ammonium bromide (CTAB) [9], and carboxy methylated cellulose (CMC) [39,40], etc.…”
