Binary and ternary polymer–strontium complexes and the capture of radioactive strontium‐90 from the polluted soil of the Semipalatinsk Nuclear Test Site

Abstract

ABSTRACT:The interaction of poly(acrylic acid) (PAA) and poly(ethylene glycol) (PEG) with strontium ions and the binding of strontium ions by equimolar interpolymer complexes (IPCs) of PAA and PEG were studied. The stability constants of binary polymer-metal complexes were determined. Aqueous solutions of IPCs of PAA and PEG were applied as soil structuring agents in model and real experiments. The ability of IPCs to capture radioactive strontium ions from the polluted soil of the Semipalatinsk Nuclear Test Site was established.

Synthesis, characterization, ion‐exchange, and antimicrobial study of poly[(2‐hydroxy‐4‐methoxybenzophenone) propylene] resin and its polychelates with lanthanides (III)

“…The results are presented in the Table IX. It reveals that the amount of metal ion taken up by the resin is increasing with an increase in concentration of NO 3 2 ClO 4 2 and Cl 2 and decreasing with an increase in concentration of SO 4 22 . This may be due to sulphate form rather strong chelates with metal, while nitrate and chloride might form weak chelates.…”

“…The La(III) polychelates were found diamagnetic in nature as expected for six coordinated octahedral geometry. The electronic spectra of Pr(III), f 3 Figure 3.…”

“…2 They have synthesized vinyl ferrocine by free radical polymerization. Chelating polymers are more interesting and play a vital role due to their applications in pollution control, 3 selective metal recovery from dilute solutions, 4,5 as protective coatings on metal surfaces or as a priming layer, coating on paper, fiber, and fabrics, and selective binding of enzymes. 6,7 Synthetic resins are being predominantly used as ion exchangers; their characteristics can be tailored to specific applications such as water purification and selective removal of waste materials in nuclear plants.…”

Synthesis, Characterization and Biological Activity of Polymer Nickel (Ii) Complex

“…Nickel (II) complexes bearing N, O-chelate ligand activation for MMA polymerization yielded poly (methyl methacrylate) (PMMA) with rich syndiotacticity microstructure [4][5][6][7][8][9][10]. The chelating polymers find applications in bioinorganic industry [11], wastewater treatment [12,13], pollution control [14], hydrometallurgy [15], preconcentration [16], anionic polyelectrolyte hydrogels [17], cation-exchange resins [18] , showed potential applications in material science as conductive [19], luminescent [20], magnetic, porous, chiral or non-linear optical materials [21], catalytic [22][23][24][25],organic synthesis [26], polymer drug graft, recovery of trace metal ions [13] and antimicrobial activities [27,28].…”

Stoichiometry of Polymer Complexes

“…Polymer complexes have found wide applications in bioinorganic industry (Fenger & Le Drian, 1998), wastewater treatment (Mizuta et al, 2000), pollution control (Orazzhanova et al, 2003), hydrometallurgy (Varvara et al, 2004), preconcentration (Ro et al, 2003), anionic polyelectrolyte hydrogels (Varghesa et al, 2001), cation-exchange resins (Ahmed et al, 2004) etc. Moreover, they recently showed potential applications in material science as catalytic, conductive, luminescent, magnetic, porous, chiral or non-linear optical materials (Janiak, 2003;James, 2003;Maspoch et al, 2004;Batten & Murray, 2003).…”
