Uranium and lead adsorption onto bentonite and zeolite modified with polyacrylamidoxime
(SPRINGER, 2012)
Polyacrylonitrile (PAN) and bentonite (B)/zeolite (Z)-PAN composites were prepared by direct polymerization of acrylonitrile (AN) and AN adsorbed onto B and Z. PAN and the composites were subjected to amidoximation procedure ...
Polyacrylamide-hydroxyapatite composite: Preparation, characterization and adsorptive features for uranium and thorium
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2012)
The composite of synthetically produced hydroxyapatite (HAP) and polyacrylamide was prepared (PAAm-HAP) and characterized by BET, FT-IR, TGA, XRD, SEM and PZC analysis. The adsorptive features of HAP and PAAm-HAP were ...
Tl-208, Pb-212, Bi-212, Ra-226 and Ac-228 adsorption onto polyhydroxyethylmethacrylate-bentonite composite
(ELSEVIER SCIENCE BV, 2012)
The adsorption of naturally occurring radionuclides (Tl-208(+), (212)pb(2+), Ra-226(2+), Bi-212(3+) and Ac-228(3+)) onto Polyhydroxyethylmethacrylate-bentonite (PHEMA-B) composite was investigated. Experimentally obtained ...
Separation of uranium and thorium in aqueous solution using polyhydroxyethylmethacrylate-hydroxyapatite novel composite
(DESALINATION PUBL, 2012)
Poly(hydroxyethylmethacrylate-hydroxyapatite) [P(HEMA-Hap)] composite was synthesized by free radical polymerization in aqueous solution. The adsorptive features of P(HEMA-Hap) composite were investigated for UO22+ and ...
Thermodynamic parameters of TI+, Ra2+, Bi3+ and Ac3+ adsorption onto polyhydroxyethylmethacrylate-hydroxyapatite composite
(SPRINGER, 2012)
In this research, a new composite, poly (hydroxyethylmethacrylate-hydroxyapatite) [P(HEMA-Hap)], was synthesized and its adsorptive features for natural radionuclides (TI+, Ra2+, Bi3+ and Ac3+ in a leaching solution) were ...
Synthesis and characterization of a new low-cost composite for the adsorption of rare earth ions from aqueous solutions
(ELSEVIER SCIENCE SA, 2012)
We synthesized and characterized a novel composite, poly(acrylamide-expanded perlite) [P(AAm-EP)] and investigated its adsorptive features for Tb3+. We achieved the synthesis by using free-radical polymerization and a ...
Removal of radio nuclides of the U- and Th- series from aqueous solutions by adsorption onto Polyacryamide-expanded perlite: Effects of pH, concentration and temperature
(ELSEVIER SCIENCE BV, 2012)
Poly (Acryamide-expanded perlite) [P(AAm-EP)1, was synthesized. The influence of process parameters: initial pH and five radio nuclides of the U- and Th- series (TI+, Ra2+, Bi3+, Ac3+ and Pb2+ in a leaching solution) ...
Synthesis and Characterization of Poly(2-hydroxyethylmethacrylate-hydroxyapatite) a Novel Composite for the Removal of Lead(II) from Aqueous Solutions
(WILEY-BLACKWELL, 2012)
In the present study, a novel adsorbent, poly (2-hydroxyethylmethacrylate-hydroxyapatite) [P(HEMA-Hap)], was prepared and characterized. The synthesis was achieved by means of free-radical polymerization and a number of ...
