Removal of Nitrate Using Synthetic Nano Composite ZnO/Organoclay: Kinetic and Isotherm Studies
This study was conducted to investigate organoclay prepared using montmorillonite clay with zinc oxide (ZnO) nanoparticles and a long-chain organic surfactant hexadecyltrimethylammonium bromide for the removal of nitrate ion from aqueous solutions. Adsorbents were evaluated by X-Ray Diffraction (XRD), Fourier Transform Infra-Red (FT-IR),...
متن کاملPhysical Chemistry Studies of Acid Dye Removal from Aqueous Media by Mesoporous Nano Composite: Adsorption Isotherm, Kinetic and Thermodynamic Studies
In this research, SBA-15/Polypyrrole (SBA-15/PPy) mesoporous nanocomposite was synthesized, characterized and applied for Acid Blue 62 (AB62) adsorption as a textile dye from aqueous solution. In order to evaluate the structural properties of synthesized adsorbent, FT-IR, FESEM and TEM images, XRD, and BET techniques were applied. Some parameters such as pH, dosage, and time which affect the ba...
متن کاملNano-graphene oxide composite for in vivo imaging
Introduction Positron emission tomography (PET) tracers has the potential to revolutionize cancer imaging and diagnosis. PET tracers offer non-invasive quantitative imaging in biotechnology and biomedical applications, but it requires radioisotopes as radioactive imaging tracers or radiopharmaceuticals. Method This paper reports the synthesis of 18F-nGO-PEG by covalently functionalizing PEG w...
متن کاملMontmorillonite as Efficient Nanoclay for Removal of Aniline Blue Dye: Optimization, Isotherm and Kinetic Study
In this study, montmorillonite clay was used as the adsorbent for the removal of Aniline Blue dye, from aqueous solution by the batch adsorption technique under different conditions. The maximum removal of aniline blue dye for initial dye concentration 20 mg/L was more than 95% at optimum conditions (pH=4.5, contact time=30 min, and adsorbent dosage=2 g/L). The data of this study were fitted wi...
متن کاملRemoval of Nickel (II) ions from aqueous solutions using Iron (III) oxide nanoparticles: study of kinetic, isotherm and thermodynamic models
Background and Objective: Due to the existence of industries such as stainless steel, the presence of nickel (II) ions in water and wastewater has been reported at high concentrations. Removal of nickel (II) ions from wastewater and the environment are of primary importance. In this study, iron (III) oxide nanoparticles were studied as an adsorbent for removal of Ni (II) ions from water in the ...
