Although the inhibitory effects of different biocides continue to gain ever-increasing importance, the corrosion inhibition of petroleum steel in the Black Sea water by such compounds remains largely uncharacterized. Thus, to study the effect of sulfate-reducing bacteria, corrosion parameters in oxygen-free medium contaminated with sulfur have been determined. The variation of corrosion rates with the addition of two biocides, glutaraldehyde (GA) and ammonium chloride (AC), has been determined by using Tafel extrapolation and linear polarization methods in sulfur-polluted seawater, both with and without biocides. Overall, this experimental work, also corroborated by theoretical data, reveals that some concentrations of GA and AC act as effective biocides in sulfur-polluted medium.
