The effect of chloride ions and A. ferrooxidans on the oxidative dissolution of the chalcopyrite evaluated by electrochemical noise analysis (ENA)
(2009-12-28)
It is believed that the dissolution of chalcopyrite (CuFeS2) in acid medium can be accelerated by the addition of Cl- ions, which modify the electrochemical reactions in the leaching system. Electrochemical noise analysis ...
Poly(vinyl chloride) membrane electrodes for the determination of the antibiotic tiamulin
(Japan Soc Analytical ChemTokyoJapão, 1997)
Calibration of boundary conditions correlated to the diffusivity of chloride ions: An accurate study for random diffusivity
(2022-02-01)
For reinforced concrete (RC) structures, the corrosion of the reinforced steel bars from chloride ions is a periodic risk. The chloride ions diffusion is governed by Fick’ laws, however, these equations can be applied under ...
A full-atom multiscale modelling for sodium chloride diffusion in anion exchange membranes
(Elsevier Science, 2021-11)
A novel full-atom multiscale method, combining different computational approaches and aimed to describe diffusion of multiple ions in anion exchange membranes (AEM), is presented. The method is used to evaluate diffusion ...
Hexacyanoferrate ion adsorbed on propylpyridiniumsilsesquioxane polymer film-coated SiO2/Al2O3: use in an electrochemical oxidation study of cysteine
(Pergamon-elsevier Science LtdOxfordInglaterra, 2003)
Nitrite corrosion inhibition in chloride-rich electrolytes correlated to the electrical properties of surface films on carbon steel
(Elsevier, 2019-12)
The electronic properties and the composition of surface films grown in pore simulating solutions are studied using various electrochemical and surface techniques and then correlated to the inhibiting efficiency of nitrite ...
Chloride diffusion assessment in RC structures considering the stress-strain state effects and crack width influences
(2019-03-20)
The aim of this study is to investigate the chloride ions diffusion in sound and cracked concrete under compressive loads. The model includes the analytical setup and data analyses. The governing equations are modified to ...
Evaluation and comparison of traditional methods and Electron Probe Micro Analysis (EPMA) to determine the chloride ingress perpendicular to cracks in self-healing concrete
(Elsevier, 2019-12)
The appearance of cracks in reinforced concrete structures accelerates the penetration of aggressive substances such as chloride ions into the concrete matrix. This leads to durability problems due to the accelerated onset ...
Phosphate ions as effective inhibitors for carbon steel in carbonated solutions contaminated with chloride ions
(Pergamon-Elsevier Science Ltd., 2016-10-30)
This investigation focuses on sodium biphosphate (Na2HPO4) as corrosion inhibitor for construction steel. All the tests are carried out in a solution that simulates the composition of the pores in chloride-contaminated ...
