Wang, Junlei; Hou, Baoshan; Xiang, Jun; Chen, Xuedong; Gu, Tingyue; Liu, Hongfang published the artcile< The performance and mechanism of bifunctional biocide sodium pyrithione against sulfate reducing bacteria in X80 carbon steel corrosion>, Quality Control of 3811-73-2, the main research area is sulfate reducing bacteria corrosion carbon steel sodium pyrithione inhibitor.
Anti-bacterial and anti-corrosion properties of sodium pyrithione (SPT) were studied using exptl. methods and quantum chem. calculations SPT at 80 mg/L reduced planktonic and sessile sulfate reducing bacteria (SRB) on X80 carbon steel to undetectable levels. The corrosion inhibition efficiency of SPT against microbiol. influenced corrosion exceeded 80% based on weight loss, which was corroborated by electrochem. data. Mol. modeling showed that SPT mol. provided electrons to the unoccupied orbitals of the Fe surface with a large binding energy of SPT on the Fe (1 1 0) plane, which favored SPT adsorption on the carbon steel.
Corrosion Science published new progress about Adsorption. 3811-73-2 belongs to class pyridine-derivatives, and the molecular formula is C5H4NNaOS, Quality Control of 3811-73-2.
