Magnetic nanoparticles as effective adsorbents for the removal of heavy metals from water: a review of surface modification (2015-2022)

The use of biopolymer composite materials in the usage of magnetic nanoparticles for the removal of heavy metal pollutants has received little attention, despite their remarkable physical and chemical properties that suggested their huge potential as promising adsorbents. . Therefore, various sorben...
