Synthesis, characterization and application of triethylenetetramine modified polystyrene resin in removal of mercury, cadmium and lead from aqueous solutions

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].…”

Evaluation of chelate and cation exchange resins to remove copper ions

“…1.b.). Finally, the band 702 cm −1 deals with the presence of aromatic groups in the matrix which were not affected by the metal complexation[16][17][18].…”

Optimization of coag-flocculation processes of a newly synthesized quaternized oil palm empty fruit bunch cellulose by response surface methodology toward drinking water treatment process application

“…Other contaminants such as heavy metals, namely mercury (Hg), cadmium (Cd), chromium (Cr), and lead (Pb) which are known to be highly toxic were also found in the river water (SanzMedel 1998;Xiong and Yao 2009). The existence of these metals in surface water is predominantly associated with suspended particles.…”
