Porous Nanomaterials for Heavy Metal Removal

Fate of Fe3O4@NH2 in soil and their fixation effect to reduce lead translocation in two rice cultivars

“…Many metal oxide nanoparticles (NPS) are nontoxic and low-cost materials which have also been researched as heavy metal adsorbents widely. Except ease of recovery and reusability, they have minimized environmental impact and unique advantages including large surface area and high surface activities due to the size-quantization effect (Lee, Zaini, & Tang, 2017). In general, the process and mechanism of metal adsorption on Fe 3 O 4 -NPS could be explained from surface interaction, including metal complexation, electrostatic interactions, micro precipitation, and ion exchange (Pu et al, 2018).…”
