Abstract
Five synergistic combinations of biocides were found, among which the combination of
kathon + copper sulfate was the most efficient against Serratia marcescens. Depending on the
ratio of these biocides, the synergistic effect of this pair allowed 4-20-fold decreases in the
effective concentrations. Combinations of biocides with salts (carbonates and phosphates) that
facilitate passivation of steel were found, which considerably decreased the corrosion losses of
mild steel in comparison to isolated treatment with biocides or salts. The data showed that biocides
must be added to corrosion-prone systems simultaneously with the beginning of their exploitation.
Otherwise, considerably excessive amounts of biocides or their synergistic compositions are needed. |
