Arsenate adsorption on waste eggshell modified by goethite, alpha-MnO2 and goethite/alpha-MnO2
(Chemical Engineering Journal, 2014)
An efficient adsorbents for arsenate removal was developed by modification of calcined eggshell with goethite (calcined eggshell/goethite; sorbent 1), alpha-MnO2 (calcined eggshell/alpha-MnO2; sorbent 2) and hybride system ...
Ultrasonic assisted arsenate adsorption on solvothermally synthesized calcite modified by goethite, alpha-MnO2 and goethite/alpha-MnO2
(Ultrasonics Sonochemistry, 2014)
A highly porous calcium carbonate (calcite; sorbent 1) was used as a support for modification with alpha-FeOOH (calcite/goethite; sorbent 2), alpha-MnO2 (calcite/alpha-MnO2; sorbent 3) and alpha-FeOOH/alpha-MnO2 ...
Adsorption thermodynamics of organics on nickel- and copper-hexacyanoferrates
(Materials Science Forum, 1998)
Adsorption of various organics on Ni- and Cu-hexacyanoferrates was investigated by gas-solid chromatography (inverse gas chromatography). Adsorption was studied in the temperature region from 80 to 95 degrees C at zero ...
Surface characterization of mesoporous carbon cryogel and its application in arsenic (III) adsorption from aqueous solutions
(Microporous and Mesoporous Materials, 2015)
Resorcinol-formaldehyde (RF) cryogels were synthesized by sol-gel polycondensation of resorcinol with formaldehyde and freeze-drying was carried out with t-butanol. Carbon cryogel (CC) was obtained by pyrolyzing RF cryogels ...
Adsorption of some weak organic electrolytes from aqueous solutions on silica
(Materials Science Forum, 2007)
The adsorption of organic electrolytes from aqueous solutions on various adsorbents has been frequently investigated because of its importance in water purification. Phenol and substituted phenols are very common contaminants ...
Adsorption of Tiron onto alumina
(Materials Science Forum, 2005)
It has been shown recently that small organic molecules, used as dispersants in the colloidal processing of ceramic powders to adjust the forces between the particles, are quite efficient in preparing aqueous suspensions ...
Preparation and Characterisation of Novel Biodegradable Material Based on Chitosan and Poly(Itaconic Acid) as Adsorbent for Removal of Reactive Orange 16 Dye from Wastewater
(2015)
Environmental protection has been a topic of great interest in recent years. Discharging azo dyes in aquatic systems contaminates water and causes serious ecological problems. Azo dyes are bio-accumulative, and, due to ...
Characterization of chitosan/montmorillonite membranes as adsorbents for Bezactiv Orange V-3R dye
(Journal of Hazardous Materials, 2012)
The synthesis, characterization and environmental application of chitosan/montmorillonite membrane for adsorption Bezactiv Orange V-3R were investigated. Chitosan/montmorillonite membranes were synthesized in different ...
Removal of Tc-99(VII) by organo-modified bentonite
(Applied Clay Science, 2014)
(99)Technetium is one of the largest components of nuclear waste material. In aqueous solutions Tc-99 is present as the pertechnetate oxoanion, (TcO4-)-Tc-99, which is highly soluble and mobile in groundwater under oxidizing ...
Adsorptive Removal of Technetium-99 Using Macroporous Poly(GMA-co-EGDMA) Modified with Diethylene Triamine
(Journal of Applied Polymer Science, 2012)
dThe possibility of sorption of technetium-99 in the form of pertechnetate anion (TcO(4)(-)) and the sorption kinetics for removing TcO(4)(-) from aqueous solution by chelating polymers based on glycidyl methacrylate (GMA) ...
