“…Clearly, in the UV/Cl 2 DWDS, the diameter of the impedance loops markedly increased with time, indicating a decrease of the corrosion rate after 50 d. However, in the Cl 2 alone DWDS, the diameters of impedance loops decreased from 50 d to 140 d, and later increased with time, indicating that the corrosion rate was accelerated before 140 d, then the corrosion rate decreased. Furthermore, according to a described method (Gerengi et al, 2009), all impedance spectra were analyzed with an equivalent circuit, where R s refers to resistance of electrolytes in bulk, Rct refers to charge transfer resistance at metal surface, W refers to Warburg impedance, Q refers to constant phase element of the electrical double layer (Fig. S6).…”

Corrosion DisinfectionWater quality Drinking water distribution system a b s t r a c tThe effect of UV/Cl 2 disinfection on the biofilm and corrosion of cast iron pipes in drinking water distribution system were studied using annular reactors (ARs). Passivation occurred more rapidly in the AR with UV/Cl 2 than in the one with Cl 2 alone, decreasing iron release for higher corrosivity of water. Based on functional gene, pyrosequencing assays and principal component analysis, UV disinfection not only reduced the required initial chlorine dose, but also enhanced denitrifying functional bacteria advantage in the biofilm of corrosion scales. The nitrate-reducing bacteria (NRB) Dechloromonas exhibited the greatest corrosion inhibition by inducing the redox cycling of iron to enhance the precipitation of iron oxides and formation of Fe 3 O 4 in the AR with UV/Cl 2 , while the rhizobia Bradyrhizobium and Rhizobium, and the NRB Sphingomonas, Brucella producing siderophores had weaker corrosion-inhibition effect by capturing iron in the AR with Cl 2 . These results indicated that the microbial redox cycling of iron was possibly responsible for higher corrosion inhibition and lower effect of water LarsoneSkold Index (LI) changes on corrosion. This finding could be applied toward the control of water quality in drinking water distribution systems. ª 2014 Elsevier Ltd. All rights reserved. IntroductionIron and steel pipes have been used in water distribution systems for several centuries throughout the world, and are subjected to corrosion, causing deterioration of potable water quality due to unwanted chemical and biochemical reactions (McNeill and Edwards, 2001; Husband and Boxall, 2011). In the corrosion processes of iron pipes, iron ions were released into distributed water, and can re-precipitate forming corrosion scales, also referred to as tubercles (Gerke et al., 2008). The processes can greatly affect water quality in distribution system, not only by releasing iron oxyhydroxides (red water), but also by reactions with e.g. chlorinated disinfection byproducts (Chun et al., 2005), nitrates (Hansen et al., 1996) or natural organic matter (NOM) (Nawrocki et al., 2010 Available online at www.sciencedirect.com ScienceDirect journal homepage: www.else vier.com/locate /wa tres w a t e r r e s e a r c h 6 0 ( 2 0 1 4 ) 1 7 4 e1 8 1http://dx

“…For all the studied compounds, the impedance diagrams display one single capacitive loop represented by a slightly depressed semicircle. This capacitive loop indicates that the corrosion of the alloys in 3%, 6% and 9% concentrations of Na 2 B 4 O 7 ·5H 2 O solution is mainly controlled by the charge transfer process and the formation of an adsorption layer on the metal surface [27]. All experimental spectra were fitted with an appropriate equivalent circuit (Figure 2) in order to find the parameters which described and were consistent with the experimental data.…”

The corrosion behaviour of AISI 316 and AISI 304 stainless steels in Na 2 B 4 O 7 ·5H 2 O solutions with various concentrations (3%, 6% and 9% w/w) commonly used in wood industry was investigated by using electrochemical impedance spectroscopy and polarisation techniques. The results reveal that the dissolution pattern of the studied steel samples is in the order 3% > 6% > 9%. The AISI 316 stainless steel is found to exhibit better corrosion resistance than the 304-type stainless steel alloy.
