“…Then all surfaces are dried at 105 • C for 24 h. Also all surfaces were washed with distilled water several times to remove dust and other water-soluble impurities. The same process for preparation of the surfaces was reported frequently [36][37][38][39]. P(HEMA) and P(MMA-HEMA) were used as similar disk-shaped sheets of 1 g of weight.…”

“…The active surface is unavailable in the fine pores of porous sorbents when large solute molecules or suspensions are present in wastewater. Accordingly, Denizli15 prepared the water‐swellable poly(ethylene glycol dimethacrylate‐hydroxyethyl methacrylate) microbeads with a new ligand, congo red, to overcome this problem. However, preparing a versatile chelating resin is easier if the vinyl monomers contain a chelating group.…”

ABSTRACT:The chelating resins have high potential applications for the selective removal and recovery of metal ions from industrial waste solutions. The hydrophilic acrylate monomer with the iminodiacetic acid chelating group was prepared from glycidyl methacrylate and iminodiacetic acid at 60°C. The microbeads, prepared from acrylate monomer with the iminodiacetic acid chelating group, were employed by inversion suspension polymerization. In the pH range of 2-6, a reasonably good equilibrium sorption capacity is maintained for Cr 3ϩ (ca. 2.7 mmol/g) and Cu 2ϩ (ca. 1.8 mmol/g) in the chelating resins. The adsorption of Cd 2ϩ and Pb 2ϩ on microbeads is clearly affected by the pH of the solution, such that these ions' adsorption capacity increased with the pH of the aqueous solution. The adsorption of Cd 2ϩ (ca. 1.25-1.87 mmol/g) and Pb 2ϩ (ca. 0.99 -1.89 mmol/g) showed a maximum at approximately pH ϭ 5 and 6, respectively. The adsorption isotherms of Cr 3ϩ and Cu 2ϩ adsorbed on microbeads were following the Langmuir isotherm, but the adsorption behavior of Cd 2ϩ and Pb 2ϩ were not. The concentration of alkaline earth-metal cations on the range of 0 -200 ppm had no influence on metal ions adsorbed capacity of chelating resins. Additionally, NTA (nitrilotriacetic acid) had no significant influence on metal ion adsorption by chelating resins. Furthermore, phenol pollutant can be adsorbed effectively by metal ions chelated microbeads; therefore, the microbeads were useful not only in recovering metal ions but also in the treating phenol pollutants in wastewater.

“…As seen here, chemical structures of dye molecules are different from each other, and contain several active points (amino, azo, sulfonyl, and triazine groups) for chelating with Fe(III) ions. previous papers ensured incorporation of dye molecules [30][31][32][33][34]. Dye release was investigated in Fe(III) adsorption-desorption media and in human plasma.…”

Dye-incorporated [poly(EGDMA-HEMA)] microspheres were investigated as a new chelate-forming polymer for iron overload. Poly(EGDMA-HEMA) microspheres, in the size range of 150-200 microm, were produced by a modified suspension polymerization of EGDMA and HEMA. The reactive dye-ligands (i.e. Cibacron Blue F3GA, Alkali Blue 6B and Congo Red) were covalently incorporated to the microspheres. The maximum dye incorporations were 16.5 micromol Cibacron Blue F3GA g(-1), 23.7 micromol Alkali Blue 6B g(-1), and 14.5 micromol Congo Red g(-1). The maximum Fe(III) adsorptions on the dye-incorporated microspheres from aqueous solutions containing different amounts of Fe(III) ions were 51.0, 37.3, and 25.1 mg g(-1) for the Cibacron Blue F3GA, Alkali Blue 6B, and Congo Red carrying microspheres, respectively. The maximum Fe(III) adsorptions were observed at pH 4.0 in all cases. Fe(III) removal from human plasma was also investigated. The maximum adsorption capacities of Fe(III) ions from human plasma for Cibacron Blue F3GA, Alkali Blue 6B, and Congo Red, were of 12.0, 7.5, and 3.8 mg g(-1) polymer, respectively. It was observed that Fe(III) could be repeatedly adsorbed and desorbed without significant loss in adsorption capacity.
