THE importance of copper ions in natural redox systems is well known. For example, the oxidation of diphenols by molecular oxygen occurs by way of a Cu(I) to Cu(II) oxidation in the diphenol oxidase.

The interaction mechanism between copper and propionic acid vapors is shown. Exposures were carried out to various pollutant concentrations and times. Cathodic scan, x-ray diffraction (XRD) and ...

2009; Borkow, 2015; Rangel et al., 2020). Copper oxide presents itself in two forms: copper I oxide (Cu 2 O) is less stable than copper (II) oxide (CuO) at room temperature, as CuO has a monoclinic ...
