Abstract
The polyacrylamide was investigated for controlling of corrosion and microbial corrosion of mild steel in salty media. Both the corrosion inhibition efficiency and biocidal activity are measured at different concentrations of polyacrylamide. The electrochemical measurements are used to monitor the corrosion results and the serial dilution method is used to detect the biocidal activity. The results showed that the polyacrylamide is improved the biocidal activity corrosion resistance for mild steel with increasing the concentration. The biocidal activity was subjected to the planktonic and sessile bacteria and the obtained results proved that the killing effect of polyacrylamide is shows higher efficiency in planketoinc more than the sessile bacteria. The corrosion data proved that, the inhibitor shows acceptable effect against corrosion in chloride solution and the effect is also depends on the inhibitor concentration. The best result in both corrosion and microbial corrosion is obtained at concentration of 15 ppm.
