function of pH. Zeta potential measurements identified an amphoteric behavior for the Fe-Ni/Zn/βCD, suggesting its better capability to remove ions (cations and anions) from aqueous solutions compared to that of Fe-Ni/Zn.

βCD crystals described previously in the literature [29], confirming the presence of the macromolecule in the ferrite nanoparticles matrix. SEM images, Figure 2c and Figure 2d, demonstrate larger assembledparticles (above 500 nm). It is interesting to note that when βCD is used to prepare the ferrite
