Removal of uranyl ions in aquatic mediums by using a new material: Gallocyanine grafted hydrogel
(ELSEVIER SCIENCE BV, 2013)
A new material containing gallocyanine (GC) grafted polyacyril amide (PAA) was synthesized and its adsorption ability was examined for the removal of uranyl ions from aqueous media. The new developed adsorbent was characterized ...
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 ...
Modification of natural zeolite with NaOH for removal of manganese in drinking water
(ELSEVIER SCIENCE BV, 2016)
Natural zeolite (NZ) obtained from the Manisa-Demirci region of Turkey was modified by NaOH aqueous solutions (0.5-2.0 mol/dm(3)) and the adsorption capacity of natural and modified forms was determined for manganese ...
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 ...
Removal of some cationic dyes from aqueous solution by acrylamide- or 2-hydroxyethyl methacrylate-based copolymeric hydrogels
(KOREAN FIBER SOC, 2017)
In this study, anionic hydrogels were prepared using a crosslinker (N,N'-methylenebisacrylamide) through a free radical addition reaction in aqueous solutions of neutral acrylamide or 2-hydroxyethyl methacrylate monomer ...
Synthesis of a Useful and Economic Polymeric Material for Effective Removal of Bisphenol A
(SPRINGER/PLENUM PUBLISHERS, 2018)
A composite material containing polyacryl amide (PAA) and lignin (L) was developed and characterized for effective Bisphenol A (BPA) removal. Fundamentals of the proposed approach is based on adsorption of BPA molecules ...
Effect of alkali-treatment on the characteristics of natural zeolites with different compositions
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2018)
A series of natural zeolites with different compositions were modified by post-synthesis modification with sodium hydroxide (NaOH) solution. Natural and modified zeolites were characterized by XRD, SEM, nitrogen adsorption, ...
Theoretical insight into an empirical rule about organic corrosion inhibitors containing nitrogen, oxygen, and sulfur atoms
(ELSEVIER SCIENCE BV, 2017)
Steel is an important material in industry. Adding heterocyclic organic compounds have proved to be very efficient for steel protection. There exists an empirical rule that the general trend in the inhibition efficiencies ...
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 ...
Uranyl Ions Removal by Quercus macrenthera Gall's Extract-Based Cryogels with Extreme Characteristics
(WILEY, 2014)
In this study, one type of oak galls (galls of Quercus macrenthera, QMG) was used as tannin source for the production of tannic acid-based cryogels (CRGs). QMG-CRGs were characterized with scanning electron microscopy and ...
