ICMT Research Recognized by an Editor’s Choice Open Access Article: Determining Critical Micelle Concentration of Organic Corrosion Inhibitors and its Effectiveness in Corrosion Mitigation

ICMT is pleased to announce that Dr John Scully has selected our paper Determining Critical Micelle Concentration of Organic Corrosion Inhibitors and its Effectiveness in Corrosion Mitigation (hyperlink) as his editor’s choice open access article from the current issue of Corrosion. The work described therein constitutes a core component of first author Negar Moradighadi’s doctoral research, featuring contributions from then undergraduate researcher Starr Lewis and recent ICMT alum Juan Dominguez Olivo.

As a rule-of-thumb, critical micelle concentration (CMC) of a surfactant corrosion inhibitor has been considered an important indicator of its corrosion mitigation efficiency. In our paper, we describe the synthesis, characterization, and CMC determinations for a range of benzyldimethylalkylammonium model compounds possessing tail lengths ranging from C4 to C16; surface tension (indirect) and fluorescence spectroscopy (direct) methods were employed for micelle detection, the latter demonstrating weakness compared with the former for CMC determination. As shown below in Table 5 from the paper, no clear correlation between CMC and maximum inhibition of the corrosion rate was observed in a CO2-containing aqueous environment.
