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 ...
Mono and simultaneous removal of crystal violet and safranin dyes from aqueous solutions by HDTMA-modified Spirulina sp.
(INST CHEMICAL ENGINEERS, 2016)
The process of mono and binary removal of crystal violet and safranin dyes by Spirulina sp. (blue-green algae) modified with cationic surfactant is evaluated. The surfactant used was hexadecyltrimethylammonium bromide ...
Adsorptive features of polyacrylamide-apatite composite for Pb2+, UO22+ and Th4+
(ELSEVIER SCIENCE BV, 2009)
Micro-composite of polyacrylamide (PAA) and apatite (Apt) was prepared by direct polymerization of acrylamide in a suspension of Apt and characterized by means of FT-IR, XRD, SEM and BET analysis. The adsorptive features ...
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) ...
The use of polyacrylamide-aluminosilicate composites for thorium adsorption
(ELSEVIER SCIENCE BV, 2011)
The adsorption of Th4+ ions was studied on composites of polyacrylamide (PAAm) with montmorillonite (Mt), clinoptilolite (Z) and zeolite Y (ZY), and after phytic acid (Phy) modification. The monolayer adsorption capacity ...
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 ...
Organoclay modified with lignin as a new adsorbent for removal of Pb2+ and UO2 (2+)
(SPRINGER, 2014)
This study investigated a new adsorbent prepared from lignin modified organoclay for the removal of Pb2+ and UO2 (2+) from aqueous solutions. The characterization of new adsorbent was performed by FT-IR and XRD. Adsorption ...
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 ...
