This study targets the investigation of three pyrimidine-bichalcophene derivatives (MA-1230, MA-1231, MA-1232) for prevention corrosion on copper in 1 M HNO3via weight loss (WL), potentiodynamic polarization (PDP), and electrochemical impedance spectroscopy (EIS) techniques. The surface morphology was also analyzed by different methods. It found that inhibition efficiency (% η) increased increasing doses pyrimidine temperature medium. Weight data revealed better adsorption MA-1232 Cu at...
A Novel 5,10,15,20-tetra (thiophen-2-yl) porphyrin (P1) and 5,10,15,20-tetrakis (5-Bromothiophen-2-yl) (P2) were successfully synthesized, their chemical structures proved based on its correct elemental analysis spectral data (IR 1H-NMR). These compounds examined as corrosion inhibitors for stainless steel 304 (SS304) in 2 M HCl utilizing mass reduction (MR) electrochemical tests at inhibitor concentration (1 × 10-6-21 10-6 M). The protection efficiency (IE %) was effectively enhanced with...
Abstract Two 3D-supramolecular coordination polymers (SCP1 & SCP2) have been synthesized and characterized by physicochemical spectroscopic methods. In a solution of 1.0 M HCl, SCPs were used to prevent corrosion carbon steel (CS). The inhibition productivity (% η ) rises as the synthetic inhibitor dose rises, opposite is true temperature rises. study was carried out using chemical (mass loss, ML) electrochemical ( potentiodynamic polarization, PDP impedance microscopy, EIS) techniques,...
Abstract In the present work, Verbena Officinalis (VO) leaf extract was used as potential corrosion inhibitor for of carbon steel (CS) in 0.5 M H 2 SO 4 medium. Further, inhibiting nature VO towards CS evaluated using mass loss (ML), potentiodynamic polarization (PDP), electrical impedance spectroscopy (EIS) and surface morphological analyses atomic force microscope (AFM) X-ray photoelectron (XPS) techniques. Calculation activation energy $$\left( {{\text{E}}_{{\text{a}}}^{*} } \right)$$...
Abstract Aluminum corrosion inhibitors “{[CuI (CN) 2 (phen) CuII (phen)]5H O},(MOF1) and {[CuI(CN) (phen)CuII(CN) O}@TiO (MOF1@TiO ) were studied in one molar HCl solution”. The ML results for three different temperatures (25–45 °C) compared with the of PDP EIS analyses. adsorption on Al surfaces has been calculated discussed by a Langmuir isotherm. that created showed great effectiveness, noticeable increase their inhibitory efficiency as dosage was raised temperature lowered. Inhibition...
The corrosion inhibition of carbon steel in 1.0 M hydrochloric acid solution the presence some phenolic compounds such as o-aminophenol, catechol, salicaldehyde and salicylic was investigated using weight-loss method,potentiodynamic polarization electrochemical impedance spectroscopy (EIS) techniques. Results obtained showed that efficiency these increased by increasing their concentration but decreases with a rise temperature. effect KI, KSCN KBr has also been studied. apparent activation...
