“…23,25 Accordingly, there has been much effort to develop removal methods of heavy metal ions such as ion-exchange, reverse osmosis, and electrodialysis techniques, and to synthesize new adsorbing materials including metal oxides, silica and activated carbon. 23,26 Therefore, based on the high binding capacities and rapid binding rate, the melanin nanoparticles synthesized by our method can be used as an excellent material to remove heavy metal ions from contaminant water.…”

Spherical-shape melanin nanoparticles with good water-dispersibility were successfully synthesized by a simple oxidation polymerization of 3,4-dihydroxy-phenylalanin (DOPA) with KMnO 4 . Similar features to those known from natural and synthetic melanin polymers were observed from prepared melanin nanoparticles by FT-IR, UV-Vis., and ESR spectroscopic methods. Their binding ability with several heavy metal ions from aqueous solution was quantitatively investigated, and the maximum binding capacities with melanin nanoparticles to lead, copper, and cadmium ions were obtained as 2.45, 2.17 and 1.88 mmol/g, respectively, which are much larger values than those reported from natural and synthetic melanin polymers. The large binding capacity and fast binding rate of melanin nanoparticles to metal ions can make them an excellent candidate for the remediation of contaminated water.

“…[2] In the literature, for removing heavy metal ions from aqueous solutions, several techniques such as adsorption, extraction, precipitation, neutralization, dialysis, ion exchange, and complexing agent have been reported. [3] Among these various methods, adsorption of heavy metals by chelating hydrogels is widely investigated and has had many interesting achievements. [3][4][5][6][7][8][9] Metal ion chelating polymers, called polychelatogens, contain one or more electron-donor groups (Lewis bases) such as vinyl pyridine, [3] N-methacryloylhistidine, [4] N-vinyl imidazole, [10,11] benzo-18-crown-6-acrylamide, [12] polyethyleneimine, [13] dithiocarbamate, [14] thiazolidine and benzothiazole, [15,16] 8-hydroxyquinoline, [17] and acrylic acid [18] that can form coordination bonds with most of the toxic heavy metal ions (Lewis acids).…”

A novel optimized chelating hydrogel was synthesized via graft copolymerization of acrylamide and 2-hydroxyethyl methacrylate (as two-dentate chelating co-monomer) onto salep (a multicomponent polysaccharide obtained from dried tubers of certain natural terrestrial orchids) using N,N′-methylenebisacrylamide as a crosslinker and ammonium persulfate as an initiator. Reaction parameters (N,N′-methylenebisacrylamide and ammonium persulfate amounts as well as acrylamide/2-hydroxyethyl methacrylate weight ratio) affecting the water absorption of the chelating hydrogel were optimized using a systematic method to achieve a hydrogel with high swelling capacity as possible. Heavy metal ion adsorption capacity of the optimized hydrogel for metal ions [Cu (II), Pb (II), Cd (II), and Cr (III)] were investigated in aqueous media containing different concentrations of these ions (5-50 ppm). The results showed that the hydrogel have great potential for heavy metal removal from aqueous solutions. The hydrogel formation was confirmed by Fourier transform infrared spectroscopy, and surface morphology study of the hydrogel was performed by scanning electron microscope.
