Study on adsorption, regeneration, and reuse of crosslinked chitosan graft copolymers for Cu(II) ion removal from aqueous solutions
(Desalination Publications, 2014)
This study deals with the adsorption, regeneration, and reuse of chitosan-graft-itaconic acid and chitosan-graft-crotonic acid beads for Cu(II) ion removal from aqueous solutions. For this aim, adsorption capacities, ...
Adsorption of Brilliant Green from Aqueous Solutions onto Crosslinked Chitosan Graft Copolymers
(2011)
In this study, graft copolymerization of itaconic acid (IA) and crotonic acid (CA) onto the crosslinked chitosan beads were carried out using ammonium persulfate as initiator. Grafted chitosan beads were characterized by ...
Reduction of ochratoxin a levels in white wine by yeast treatments
(John Wiley and Sons Inc., 2009)
This paper describes the abilities of 21 yeast strains isolated from six different wine-grapes of Turkey to bind ochratoxin A (OTA). Viable (108 CFU/mL) and heat-treated yeast cells were incubated both in phosphate-buffered ...
The removal of acid violet 90 from aqueous solutions using PANI and PANI/clinoptilolite composites: Isotherm and kinetics
(Springer New York LLC, 2018)
Polyaniline (PANI) and polyaniline/Gördes-clinoptilolite (PANI/GC) composite materials were synthesized by the chemical oxidative polymerization technique and used in the adsorption of Acid Violet 90 metal-complex dye (AV ...
Prediction of bromate removal in drinking water using artificial neural networks
(Taylor and Francis Inc., 2018)
In treatment of natural water resources, bromide transforms into carcinogenic bromate, especially during the ozonation process. Adsorption was used in the experimental part of this study to remove this harmful compound ...
Preparation and characterization of pH responsive poly(methacrylic acid-acrylamide-N-hydroxyethyl acrylamide) hydrogels for drug delivery systems
(John Wiley and Sons Inc., 2016)
In this study, pH responsive polymers composed of methacrylic acid, acrylamide, and N-hydroxyethyl acrylamide were synthesized by free radical polymerization technique. The characterization was done with Fourier transform ...
Synthesis of Zn(II) ion-imprinted polymeric adsorbent for selective removal of zinc from aqueous solutions
(2011)
In this study, Zn(II)-imprinted polymer microbeads were synthesized for selective removal of Zn(II) from aqueous solutions. The microbeads were prepared using methacrylic acid and 1,4-vinyl pyrrolidone as functional monomers, ...
The removal of Cu(II) and Pb(II) ions from aqueous solutions by temperature-sensitive hydrogels based on N-isopropylacrylamide and itaconic acid
(Ios Press, 2021)
This study deals with the potential use of poly(N-isopropylacrylamide-co-itaconic acid) temperature-sensitive hydrogels as an adsorbent for the removal of Cu(II) and Pb(II) ions from aqueous solutions. For this aim, the ...
Removal of Diazo Dye Direct Red 28 and Tetra Azo Dye Direct Black 22 Using Synthesized Magnetic Kaolin Supported Zinc Ferrite
(SLOVENSKO KEMIJSKO DRUSTVO, 2022)
The presence of dye molecules in water resources has harmful effects on environment. Therefore, it is important to remove dyes from wastewater using eco-friendly materials. In this study, adsorptive removal of diazo dye ...
ADSORPTION OF DIAZO DYE DIRECT RED-28 AND TETRA-AZO DYE DIRECT BLACK-22 USING CALCINED KAOLIN IN AQUEOUS SOLUTIONS
(CHEM SOC ETHIOPIA, 2023)
ABSTRACT. In this study, the removal of diazo and tetra-azo dyes using calcined kaolin were compared. Direct red-28 (DR-28) and Direct black-22 (DB-22) was chosen as diazo and tetra-azo dyes, respectively. The kaolin ...
