Inhibition of Copper Corrosion by Ethanolamine in 100 ppm NaCl

We study copper corrosion inhibition by ethanolamine (ETA)with (0, 0.2 ,0.3,0.4,0.5) vol.% concentrations in 100 ppm NaCl solution. This work is carried out by potentiodynamic measurements and Electrochemical Impedance Spectroscopy (EIS). The substrates' surface morphologies are examined by Scanning Electron Microscopy (...

Kinetics of Corrosion Inhibition of Aluminum in Acidic Media by Water-Soluble Natural Polymeric Pectates as Anionic Polyelectrolyte Inhibitors

Corrosion inhibition of aluminum (Al) in hydrochloric acid by anionic polyeletrolyte pectates (PEC) as a water-soluble natural polymer polysaccharide has been studied using both gasometric and weight loss techniques. The results drawn from these two techniques are comparable and exhibit negligible differences. The inhibition efficiency was found to increase with increasing inhibitor concentrati...

Kinetics of soluble chromium removal from contaminated water by zerovalent iron media: corrosion inhibition and passive oxide effects.

Permeable reactive barriers containing zerovalent iron are being increasingly employed for in situ remediation of groundwater contaminated with redox active metals and chlorinated organic compounds. This research investigated the effect of chromate concentration on its removal from solution by zerovalent iron. Removal rates of aqueous Cr(VI) by iron wires were measured in batch experiments for ...
