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 ...
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 ...
Effective mercury removal using a new developed polymer containing 2-(2? thiazolylazo) p-cresol
(2016)
A new material containing 2-(2? thiazolylazo) p-cresol (TAC) grafted poly acrylamide (PAA) was prepared and its adsorption ability was studied for the removal of inorganic mercury from aqueous media. Adsorption of Mercury ...
Production and characterisation of biochar from tea waste and its nickel removal capacity from aqueous solutions
(Inderscience Enterprises Ltd., 2017)
Biochar, a carbon-rich solid product of slow pyrolysis of biomass, has gained interest due to its application in the various aims. Investigating of adsorption properties of biochar for removing pollutants from waste water ...
