Bath, galvanic

Industrial Applications. Perfluoroacylbenzene sulfonates, used as additives in fire-extinguishing compounds and galvanizing baths have been prepared (88). Perfluoroacylbenzenesulfonate salts prepared by Friedel-Crafts reaction of perfluoroacyl haUdes and benzene, and subsequent sulfonation have been used as surfactants (89).

Cyanide ion-selective electrode As demonstrated in chapter 3.4, the dissolution of a halide ISE in the presence of some complexing agents, especially cyanide, can be used for determination of these agents [312, 392, 434]. An iodide ISE can be used as a cyanide ISE. The principal application of this electrode is in the determination of cyanides in waters [60, 126, 281, 336] and in galvanic baths [222, 225].

To demonstrate this influence, the nickel contents of several plants species growing on the permanent grassland of the riverside of a stretch of water contaminated by galvanic baths are detailed in Table 6.18. 

Corrosion studies of the CrFeSi compound in an industrial galvanizing bath (containing aluminium) were conducted by [2005Liu]. During these experiments it was shown that a layer of Fe-Cr-Al alloys was formed at the surface conferring good resistance against corrosion.

Some of the factors affecting film formation and subsequent changes have been analyzed in experiments in recent years in relation to atmospheric exposure and are, therefore, discussed in Chapter 2. In dry air, a film of zinc oxide is initially formed by the influence of the atmospheric oxygen (e.g., at a speed of approximately 40 nm/24 h when a part leaves the galvanizing bath). The subsequent reactions with the atmosphere are complicated and more often than not depend on the local climate or microclimate. Therefore, the formation of an insoluble zinc patina is irregular both in place and in time. But when the zinc surface becomes wet with rain, mist, or dew, the atmospheric carbon...
