The Production of Silver Nanoparticles and Their Effect on Sulfate Reducing Bacteria Under Steel Microbial Corrosion
The production of silver nanoparticles was carried out in an aqueous medium treated by discharge of the contact non-equilibrium low-temperature plasma in the presence of sodium alginate (1.25–5.0 g/l). The formation of silver metal particles (to 100 nm) was confirmed by X-ray diffraction and IR spectroscopy analysis. The obtained colloidal solutions of silver nanoparticles lead to the formation of thinner biofilm under microbial corrosion of mild steel, initiated by sulfate reducing bacteria of Desulfomicrobium genus.
