Two novel triazine-based quaternary ammonium salt Gemini surfactants as potential corrosion inhibitors for carbon steel in a sulfate-reducing bacteria solution: Experimental and theoretical studies.

In this paper, two triazine ring-containing quaternary ammonium salt Gemini surfactants (C-2-C and C-2-C) were synthesized. The minimum inhibitory concentrations against sulfate-reducing bacteria (SRB) of C-2-C, C-2-C and dodecyl dimethyl benzyl ammonium chloride (1227) were determined using the double-dilution method. The performance of C-2-C and C-2-C in inhibiting carbon steel corrosion in the presence of SRB was examined, with 1227 serving as a control sample.
