Corrosive synergic effects of acetic acid and atmospheric pollutants on lead and zinc

Abstract

Abstract The aim of this paper was to evaluate the possibility of presence of the synergic corrosive effect between acetic acid and chosen air pollutants such as: Cl2, SO2, NaCl, H2S, NH3, NOx. The metals chosen for following experiments were lead and zinc as they are known to be sensitive to volatile organic compounds. Acetic acid occurs often at indoor environment, where other pollutants may be present. The idea was to describe the influence of other pollutants on increasing the corrosion aggressivity of atmosphere contaminated by acetic acid. Synergic effect was found on lead for following pollutants: sulphur dioxide, chlorine, ammonia and nitrogen oxides. And on zinc the found pollutants are: sodium chloride, sulphur dioxide, chlorine, hydrogen sulphide and nitrogen oxides.
