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 ...
Removal of copper from aqueous solutions by phosphate rock
(2005)
A study was carried out to examine the removal of copper from an aqueous solution by phosphate rock (PR). The adsorption method was applied and optimum conditions for adsorption were evaluated by changing various parameters; ...
Removal of phenoxyacetic acid based herbicides by crosslinked poly(N-vinyl pyrrolidone)
(1996)
In this study, binding of herbicides such as p-chlorophenoxyacetic acid, 2,4-dichlorophenoxyacetic acid and the ammonium salt of 2,4-dichlorophenoxyacetic acid onto poly(N-vinyl pyrrolidone) and the adsorption of these ...
