摘要

The synergistic effect caused by molybdate ions and biocide on the inhibition of mild steel corrosion and scale in simulated-cooling water system in the presence of a newly synthesized oxazoline derivative, namely, 2-phenyl-4-methyl-4((tetrazol-5-yl)methyl)oxazoline (OXA) has been studied using potentiodynam-ic polarization and electrochemical impedance spectroscopic method. The obtained results show that OXA inhibits the corrosion in the considered medium. The corresponding inhibition efficiency increases with inhibitor concentration and also by addition of molybdate ions. The increase of inhibiting efficiency in the presence of MoO2-/4 indicates enhancement of OXA adsorption onto the metallic surface. Moreover, the effect of biocide, namely, cetyl trimethyl ammonium bromide on biofilm formation has been studied.
