Inhibitors polarization diagrams

Fig. 14.2 (a) Polarization diagram illustrating the polarization effect of an anodic inhibitor and (b) polarization diagram illustrating the effect of an anodic passivation. 

Fig. 14.3 Polarization diagram illustrating the effect of mixed inhibitors.

Figure 17.3. Polarization diagram for steel corroding in pickling acid with and without inhibitor.

The effect of inhibitor on the metal/electrolyte system can be successfully evaluated from the polarization diagrams discussed in Chapter 2. 

Figure 14-11 Schematic diagram of the active site of the pyruvoyl enzyme histidine decarboxylase showing key polar interactions between the pyruvoyl group and groups of the inhibitor O-methylhistidine and surrounding enzyme groups. Aspartate 63 appears to form an ion pair with the imidazolium group of the substrate.268 Hydrogen bonds are indicated by dotted lines. See Gallagher et al.269...
