The influence of some salts of alkylphenol sulfonic acid on the St3 steel corrosion and electrochemical parameters was studied with the methods of polarization curves and electrochemical impedance spectroscopy. It is determined that the studied compounds possess the inhibiting characteristics in the shown system alongside with the previously determined useful characteristics. It is clear that by the influence of these compounds the values of electrochemical parameters I k and C gcconsiderably are reduced, the values of the parameters R n, R c, Bc, Ba are increased, and the value of E cor is shifted to the positive direction. It is also determined that the investigated inhibitors belong to mixed type inhibitors.
