Mercury removal from wastewater using a poly(vinylalcohol)/poly(vinylimidazole) complexing membrane

Study on the adsorption of Ca2+, Cd2+ and Pb2+ by magnetic Fe3O4 yeast treated with EDTA dianhydride

“…The pH of the aqueous solution plays an important role with respect to adsorption because it influences not only the metal species distribution in solution but also the surface properties of the EFB [28,29]. The effect of pH on the adsorption capacity of EFB for Ca 2+ , Cd 2+ , and Pb 2+ in the pH ranging from 2 to 6 (for Pb 2+ from 2 to 5.5) is presented in Fig.…”

Preparation of porous resin with Schiff base chelating groups for removal of heavy metal ions from aqueous solutions

“…Chelating polymers possess functional groups that comprise one or more donor atoms acting as a ligands towards certain types of cations. These polymers usually show higher selectivity to metal cations than ionic polymers, therefore they have been used for transition metal ion separation [19][20][21][22][23][24].…”

Removal of Hg(II) from aqueous solutions using a novel impregnated resin containing 1-(2-thiazolylazo)-2-naphthol (TAN)

“…In the recent decades, chelating ion exchange resins has been reported to be effective solid adsorbents for removal of metal ions, including Hg(II), from their aqueous solutions [10][11][12][13][14][15][16][17][18][19][20]. For providing chelating ion exchange resins, appropriate extractant molecules can be chemically bonded to or impregnated onto macroporous polymeric matrixes such as Amberlite XAD series resins.…”

“…Among them, sorption has been found to be superior to other techniques for effective mercury emission control in terms of cost, simplicity of design, ease of operation and reusability [8][9][10][11][12][13].…”
