3.1. Plackett–Burman Design A PB-12 design was performed to determine the factors affecting the synthesis of struvite. The experimental matrix with coded and actual factors for the response (Prec) is detailed in Table 2. 3.1.1. Product Characterization Figure 1 shows the phase characterization of the products obtained through the Plackett–Burman design experiments. Six experimental runs showed struvite formation (Figure 1a).

3.2. Crystal Structures Figure 3 shows the XRD results of the f-CNT (dark green line), [email protected] (blue line) and [email protected]/f-CNT (1) (red line) samples between 20° and 65° (2θ). In the f-CNT sample, position A, located at 2θ around 26°, corresponds to the typical diffraction peak of the graphitic hexagonal structure with a (002) orientation. Position B, near 43°, corresponds to graphitic planes with a (100) orientation [47].
