Adsorption phenomenon of neutral particles and a kinetic equation at the interface.

Nickel-Chitosan Hybrid as a Precursor for Nickel Oxide Nanoporous Particles for Organic Dyes Photodegredation

Hydrothermal synthesis of nickel-chitosan hybrid  has  been accomplished using Ni(CH3COO)2,4H2O, chitosan and water as starting material, template and solvent respectively, followed by calcination at 800 and 900˚C to provide nanoporous NiO800  and NiO900. The solid products were characterized by X-ray diffraction (XRD), nitrogen adsorption-desorption, scanning electron microscopy (SEM) and Four...

Electrochemical and Theoretical Studies of Adsorption of 1-H-benzotriazole at Stainless Steel in Hydrochloric acid Solution Interface as Corrosion Inhibitors

The influence of the concentration of1-H-benzoteriazolon the corrosion of 316 stainless steel (SS) in chloride acid 1M solutions was studied. The potentiodynamics polarization and scanning electron microscopy (SEM) have been used. The inhibition efficiency increased with an increase in the concentration of1-H-benzoteriazol.The adsorption of1-H-benzoteriazol onto the SS surface occurs accord...

Multi-walled Carbon Nanotube-CO-NH(CH2)2NH-SO3H: A New Adsorbent for Removal of Methylene Blue from Aqueous Media

In this study, Multi-walled carbon nanotube-CO-NH(CH2)2NH-SO3H was prepared through the functionalization of commercial multi-walled carbon nanotubes in three steps and then it was characterized using Fourier Transform Infrared Spectroscopy (FTIR) and Transmission Electron Microscopy (TEM). In addition, the adsorption of Methylene Blue was investigated by using these nanotubes. In order to remo...

Removal of Reactive Red195 Synthetic Textile Dye using Polypyrrole-coated Magnetic Nanoparticles as an Efficient Adsorbent

Magnetic Fe3 O4 nanoparticles modified by polypyrrole (PPy@Fe3 O4 MNPs) was synthesized by chemical co-precipitation method and used as an adsorbent for removal of cationic dyes, Reactive Red195, from aqueous solutions. The resulting products are characterized by scanning electron microscope (SEM) and FT-IR. The effects of solution pH value, adsorbent amount, adsorption time and capacity of the...
