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 ...
Uranium and thorium adsorption from aqueous solution using a novel polyhydroxyethylmethacrylate-pumice composite
(ELSEVIER SCI LTD, 2013)
Poly(hydroxyethylmethacrylate-pumice), [P(HEMA-Pum)], composite was synthesized by free radical polymerization in aqueous solution. The adsorptive features of P(HEMA-Pum) composite were investigated for UO22+ and Th4+ using ...
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) ...
Poly(acrylamide/maleic acid)-sepiolite composite hydrogels for immobilization of invertase
(SPRINGER, 2010)
Poly(acrylamide/maleic acid) and sepiolite (PAMS) composite hydrogel was prepared and used for the immobilization of invertase. In FTIR analysis, the characteristic bands of composite such as -OH, -COOH, Si-OH show the ...
Thallium adsorption onto polyacryamide-aluminosilicate composites: A Tl isotope tracer study
(ELSEVIER SCIENCE SA, 2010)
Adsorptive features of the composites of polyacrylamide (PAAm) and bentonite (B), and zeolite (Z) were investigated for Tl+ and TP3+. Langmuir monolayer adsorption capacities for the corresponding ions were 1.85 and 0.97 ...
Synthesis of hydroxyapatite/clay and hydroxyapatite/pumice composites for tetracycline removal from aqueous solutions
(INST CHEMICAL ENGINEERS, 2015)
Synthesized hydroxyapatite/clay (HA-C) and hydroxyapatite/pumice (HA-P) composites were used for tetracycline (TC) uptake studies from aqueous solution and their uptake capacities were compared. HA-C and HA-P composites ...
Terbium adsorption onto polyhydroxyethylmethacrylatehydroxyapatite composite and its modified composition by phytic acid
(TAYLOR & FRANCIS INC, 2014)
Hydroxyapatite (Hap) was entrapped in poly(hydroxyethylmethacrylate) P(HEMA) by direct polymerization and P(HEMA-Hap) was obtained in aqueous solution. Phytate (phy) was immobilized by phytic acid (phy) modification onto ...
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 ...
Polyacrylamide-clinoptilolite/Y-zeolite composites: Characterization and adsorptive features for terbium
(ELSEVIER SCIENCE BV, 2011)
The composites of natural (clinoptilolite) and synthetic zeolite (Z and YZ) with polyacrylamide (PAAm) were synthesized and characterized by FT-IR, TGA, XRD, SEM and PZC analysis. The adsorptive features of the minerals ...
