Abstract:
Polyaniline (PANI) thin films were successfully synthesized from a mixed solution of 1M aniline and two different concentration solutions of H2SO4 on a stainless steel substrate. The capacitance properties of polyaniline (PANI) films, have been determined and examined in the selected media of two different concentrations of H2SO4 acid using cyclic volammetry technique. Cyclic voltammetric measurements have shown that PANI films grown by cycling the potential between -0.2V and 1 V in 1M H2SO4 and 2M H2SO4 on SS electrode.

Abstract:
Ion removal is a long problem on natural freshwater resources. In order to modify the adsorption performance to remove ions from standard iron solution, natural zeolite and natural perlite were treated with deionized water (DI water) as D-zeolite and D-perlite. And, 1M sulphuric acid (H2SO4) was used to treat the adsorbent as H-zeolite and H-perlite. The capability of ion removal was preliminarily investigated from the reduction of iron in solution by X-ray fluorescence spectrometer. The result showed that treatment of adsorbents with DI water was more capability than 1M H2SO4 solution.

Abstract:
The anodic polarization behavior of Sanicro 28 austenitic stainless steels has been established in the cold worked (10 to 80% reduction in thickness) samples in 1N HCl, 1M H2SO4+ 1.5N HCl and 3N HCl solutions at room temperature. The current oscillations during the potentiodynamic scans appeared in 3N HCl implying formation of meta stable pits and this solution more severe than 1N HCl and 1M H2SO4+ 1.5N HCl. Two anodic peaks were observed in as-received and the cold worked samples in 3N HCl. In as-received state, the first anodic peak appeared at-3.95 mVSCEand the second anodic peak appeared a

Corrosion is an inevitable process of deterioration of metal but it can be slowed down using inhibitors, enhancing the durability of the metal. In the present study, the aqueous extract of Aegle Marmelos Leaves from surrounding area were tested as green corrosion inhibitor for aluminium metal in 1M H2SO4 acidic medium. The leaves extract characterization was analyzed using Fourier Transform Infrared Spectroscopy (FT-IR), the surfaces of Aluminium Sheets were examined using scanning electron microscopy (SEM) and atomic forced microscopy (AFM).

This paper investigates the effect of boronizing treatment on the corrosion resistance of API X52 steel. Borides were grown on API X52 steel in a powder mixture containing 5% B4C as a boron source, 5% NaBF4 as an activator, and 90% SiC as diluents for 4 hours at 950 °C. X-ray diffraction (XRD) analysis revealed that the sample's boride layer contains only Fe2B phases. The corrosion behavior of borided and unborided specimens was investigated using the Tafel extrapolation method in 1M HCl and H2SO4 solutions. The results show that borided specimens have better corrosion resistance than unboroni
