Abstract In the present research, the performance of MZT nano-titanate was established by combining (0.3–0.5) copper nanoparticles (0–0.5C-MZT) to improve the antimicrobial efficacy of promising engineered nanomaterials. XRD characterized the phase purity confirms the formation of magneto-zinc and copper titanates at 750 °C. The morphological features of four engineering nanoceramics were accurately described. As well, the inactivation effects of microbial growth were also evaluated for these kinds of engineered nanomaterials. After that, the disinfection of estimating four harmful waterborne bacteria in real wastewater was appraised. The results obtained of Raman active modes and FT-IR exhibit that the crystallization was strengthened by Cu doping. The natural THz response of the samples appears a distinct attenuation in the THz transmission. In addition, the results showed that 0.5C-MZT is a powerful antimicrobial agent for damaging the targeted pathogens. The results of toxicological safety tests indicated that the nanomaterials examined are safe for environmental applications. The results achieved reveal that the examined proficient dosage (200 mg/L) of studied 0.5C-MZT nanomaterials was practiced to deactivate four predominant waterborne pathogens in wastewater. Eventually, MZT could serve as a smart nano-weapon towards numerous sorts of dangerous pathogenic microbes and results; therefore, recommend that MZT can be employed as a talented disinfecting agent within wastewater processing.

Introduction The most significant necessary element for human beings is water because it is obligatory for drinking, food handling, and public health (Siddiqi et al. 2018a). In most low-income nations, drinkable water contains large quantities of organic, inorganic impurities and different classes of pathogenic * Amany M. El Nahrawy [email protected] 1
