Uptake of arsenate by an alginate-encapsulated magnetic sorbent: Process performance and characterization of adsorption chemistry

Preparation and characterization of zirconium-based magnetic sorbent for arsenate removal

“…Similar phenomena were observed for organic and inorganic arsenate sorption on the alginate-encapsulated magnetic sorbent [29,30].…”

Removal of tetracycline from aqueous solution by a Fe3O4 incorporated PAN electrospun nanofiber mat

“…This phenomenon could be linked with the buffering effect of the protonated or deprotonated iron oxide hydroxyls (Zheng et al, 2009). A similar effect was observed in other studies of Fe 3 O 4 contained sorbent (Lim et al, 2009b).…”

Removal of arsenate by cetyltrimethylammonium bromide modified magnetic nanoparticles

“…Magnetite [10,11] and magnetite-doped adsorbents such as magnetite-reduced graphene oxide composites [12] and carbon fiber/iron oxide [13] have been utilized to remove arsenic. To avoid the oxidation of magnetic nanoparticles, more recently, different methods and chemicals have been employed to modify the magnetic iron oxide nanoparticles [9,[14][15][16][17][18][19]. For example, Sayin et al [14] utilized Calix [4]arene to modify magnetic iron oxide nanoparticles.…”

“…Li et al [16] bonded chitosan to magnetic nanoparticles. Meanwhile, dimercaptosuccinic acid [17], poly-l-cysteine [9], alginate [18], as well as silica [19] have also been grafted on the surfaces of iron oxide magnetic nanoparticles.…”
