“…In all cases, similar morphologies were found. SEM micrographs reveal the formation of cubic crystals, which is in good agreement with those previously reported for samples with the same stoichiometry [27]. However, a smoother surface was found in the case of the FFC sample (Figure 6b) compared to the AFC sample (Figure 6c).…”

“…In addition, these values were similar to previously reported values as well as to the theoretical values. The obtained results show that the structure of the FeCl2•4H2O samples obtained from the water pickling liquors is in good accordance with the theoretical structure previously reported for this compound [26,27]. In order to conduct a more detailed structural characterization, XRD data were refined by the Rietveld method, where iron atoms were distributed in the 2a (0, 0, 0) positions, and chlorine, oxygen, and hydrogen were located in the 4e (x, y, z) sites.…”

“…In addition, these values were similar to previously reported values as well as to the theoretical values. The obtained results show that the structure of the FeCl 2 •4H 2 O samples obtained from the water pickling liquors is in good accordance with the theoretical structure previously reported for this compound [26,27]. According to the calculated structural parameters, the crystal structure of the obtained FeCl2•4H2O crystals structure is formed by a net of octahedra.…”

As a hazardous waste, water pickling liquors must be properly treated. An alternative consists of promoting the formation of ferrous salts from this residue due to their higher ferrous content. Since FeCl2·4H2O is widely used in several applications, obtaining pure crystals of this material appears to be an interesting prospect. However, this compound has scarcely been investigated. In the present work, FeCl2·4H2O crystals were obtained from water pickling liquors. Their structural and morphological characteristics were investigated by X-ray diffraction, scanning electron microscopy as well as Mössbauer spectroscopy. In addition, the photoluminescence study of the obtained samples was also assessed. It was observed that after some aging time, the obtained crystals changed in colour from green to more yellowish. As such, the aged sample was also evaluated, and their structural characteristics were compared with the original crystals. Despite this, the obtained crystals exhibit a FeCl2·4H2O structure, which is not modified with the aging of the sample.
