A novel green synthesis of Fe3O4 magnetic nanorods using Punica Granatum rind extract and its application for removal of Pb(II) from aqueous environment

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.…”

“…Surprisingly, the specic surface area of 3-MPA@PMNPs was much better than most of the previously reported green MPNs. [6][7][8][9][10]28,29,37,41,42 The Barrett-Joyner-Halenda (BJH) model was used to calculate the average pore size and total pore volume. The results indicated that the average pore radius of the material was 17.052 nm (the pictorial representation of the size distribution is shown in the inset of Fig.…”

“…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.…”

Structural characterization, antibacterial and catalytic effect of iron oxide nanoparticles synthesised using the leaf extract of Cynometra ramiflora

“…Few of them include the removal of heavy metals such as lead [5,6], chromium [7,8], arsenic [9], copper, zinc and manganese [10], removal dyes such as direct yellow 12 [11], M A N U S C R I P T…”

Síntesis de nanopartículas de magnetita a partir del extracto de cáscara de papaya para la degradación de colorantes azoicos en soluciones acuosas

“…La magnetita de tamaño nanométrico comprende amplias aplicaciones en biodetección, el uso futuro en tratamientos contra el cáncer [13], la catálisis y remediación ambiental [9], siendo en esta última donde las NPs se han convertido en adsorbentes de contaminantes presentes en el agua, ya que las características de estos materiales están relacionadas con la capacidad para eliminar iones de metales pesados [14] y diferentes tipos de colorantes, entre los cuales se encuentran los colorantes azoicos [15].…”
