Adsorption of malic acid at the hydroxyapatite/aqueous NaCl solution interface

Adsorption of anionic surfactant at the electrode–NaClO4 solution interface

ABSTRACT Adsorption of 1-decanesulfonic acid at the electrode-NaClO4 solution interface was determined by double-layer differential capacity measurements. At potentials less than -1,200 mV, the adsorption of the anionic surfactant on the electrode does not occur. Low concentrations of the anionic surfactant (below cmc) causes slight changes in the zero charge potential, Ez, and the surface tens...

Mixed Adsorption Layers Formed at the Electrode – Solution Interface

Nonlinear vibrational spectroscopic studies of the adsorption and speciation of nitric acid at the vapor/acid solution interface.

Nitric acid plays an important role in the heterogeneous chemistry of the atmosphere. Reactions involving HNO(3) at aqueous interfaces in the stratosphere and troposphere depend on the state of nitric acid at these surfaces. The vapor/liquid interface of HNO(3)-H2O binary solutions and HNO(3)-H(2)SO(4)-H2O ternary solutions are examined here using vibrational sum frequency spectroscopy (VSFS). ...

Adsorption Kinetics at Silica Gel/Ionic Liquid Solution Interface.

A series of imidazolium and pyridinium ionic liquids with different anions (Cl(-), Br(-), BF₄(-), PF₆(-)) has been evaluated for their adsorption activity on silica gel. Quantification of the ionic liquids has been performed by the use of RP-HPLC with organic-aqueous eluents containing an acidic buffer and a chaotropic salt. Pseudo-second order kinetic models were applied to the experimental da...

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...
