Corrsion inhibition of Aloe lateritia gel for Mild steel in 2 M HNOand 1 M HSOsolutions was investigated by potentiodynamic polarization, Scanning electron microscopy (SEM) and Foutier transform infrared (FT-IR). Inhibition efficiency increased with the increase of the concentration of the gel. ...
Characterization and quantification of the corrosion products on exposed samples were performed with Fourier transform infrared (FT-IR) microspectrocscopy, ion chromatography, X-ray diffraction (XRD), micro-balance and microscopy. At low air velocity (0.03 cm s 1) HNO 3 deposition and weight gain...
The complex index of refraction of liquid HNO3/H2O and H2SO4/HNO3/H2O has been obtained at different temperatures and acid concentrations. FT-IR specular reflectance spectra were obtained for 30, 54, and 64 wt % aqueous HNO3 and for four different H2SO4/HNO3/H2O mixtures in the temperature...
The stoichiometry and coordination structure of the extracted complex for Hf was investigated by slope analysis, Fourier transform infrared (FT-IR) spectrometry and nuclear magnetic resonance (NMR) spectrometry. It was found that HfO in nitric acid medium could be extracted into the organic phase ...
