Antibacterial and anticorrosion effects of Cetylpyridinium Chloride against Desulfovibrio desulfuricans biofilm and X80 steel corrosion

Abstract In this work, corrosion inhibition of X80 steel caused by Cetylpyridinium Chloride (CPC) in the presence of sulfate-reducing bacteria (SRB) was studied. The results showed that SRB accelerated the steel corrosion, whereas CPC had a good antibacterial activity against SRB corrosion. The growth of SRB was significantly inhibited with CPC concentration 10 mg L–1. The addition of 80 mg L–1 reduced the corrosion rate by 80 % in the presence of SRB. Molecular dynamics simulation and adsorption isotherm calculation showed that CPC can be adsorbed on the steel surface to form a protective film to protect steel form corrosion.
Highlights Desulfovibrio desulfuricans significantly accelerate the corrosion of X80 steel. CPC shows an inhibitory effect on the growth of Desulfovibrio desulfuricans. CPC effectively mitigate the MIC corrosion rate of steel. Molecular simulations proved that CPC adsorbs on steel surface to inhibit corrosion.
