Role of modification of natural zeolite in removal of manganese from aqueous solutions
(ELSEVIER SCIENCE BV, 2014)
The natural zeolite (NZ) was obtained from Sivas-Yavu of Turkey and modified by ion-exchange (NH4NO3), alkali treatment (NaOH) and addition of aluminum (Al-2(SO4)(3)). The natural and modified samples were characterized ...
Adsorption and column flotation studies on talc using anionic and cationic collectors
(SPRINGER, 2010)
Adsorption properties and column flotation were studied to investigate the interaction of the anionic and cationic collectors and flotation recoveries for talc mineral. Adsorption capacity is dependent on pH, adsorption ...
Thermodynamic parameters of TI+, Ra2+, Bi3+ and Ac3+ adsorption onto polyhydroxyethylmethacrylate-hydroxyapatite composite
(SPRINGER, 2012)
In this research, a new composite, poly (hydroxyethylmethacrylate-hydroxyapatite) [P(HEMA-Hap)], was synthesized and its adsorptive features for natural radionuclides (TI+, Ra2+, Bi3+ and Ac3+ in a leaching solution) were ...
Effects of pH, concentration and temperature on radionuclides sorption onto polyhydroxyethyl methacrylate-expanded perlite composite
(SPRINGER, 2013)
Poly (hydroxyethylmethacrylate-expanded perlite) [P(HEMA-EP)], was synthesized and its adsorptive features were investigated for natural radionuclides (TI+, Ra2+, Bi3+, Ac3+ and Pb2+) in aqueous media at differing initial ...
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 ...
Adsorption and Flotation Characteristics of the Different Types of Frothers
(TAYLOR & FRANCIS INC, 2014)
This article investigates the adsorption of different frothers onto talc particles. The adsorption and flotation characteristisc of tallow amine acetate (TAA)+frothers (MIBC and pine oil) was studied for talc mineral. In ...
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) ...
