“…Our experimental work showed that 50 ppm abiotic sulphide (depending on the sulphite and lactate concentration) caused corrosion rate ranging from 0?67 to 2?5 mm/year. This is in line with Thomas et al 51 observation that the abiotic sulphide should result in higher corrosion rate than the biotic one. This is due to the difference between the measurable and the effective biotic sulphide involved on corrosion process.…”

“…Such a slime layer could provide a barrier to the transport of corrosive species to the metal surface. An interspecies transfer of ions between bacteria could also render much of the measured sulphide unavailable to the steel 51. In contrast, all the abiotic added sulphide is able to contribute in the corrosion process.…”

The objective of this work is to study the effect of sulphide ion on the corrosion behaviour of X52 steel in the simulated solution containing sulphate reducing bacteria metabolic products species. Linear polarisation resistance and electrochemical impedance spectroscopy results show that the addition of 50 ppm sulphide ions increased the rate of X52 steel corrosion. However, with addition of 200 and 400 ppm sulphide, the corrosion rate decreased. The increase in corrosion rate is due to the increase in the cathodic reaction in the presence of sulphide, while the corrosion protection was related to FeS film formed, typically mackinawite and pyrite.
