Abstract: The morphological and dielectric properties of bioactive sol-gel alumino-copper silicate nanoporous are characterised. It is characterised by sharp diffraction peaks confirming the high crystallinity. Alumino-copper silicate was utilised as a disinfecting agent for wastewater disinfection. The growth inhibitory effect of alumino-copper silicate sanitiser was investigated against various categories of microbial pathogens. Toxicity assay of fabricated alumino-copper silicate nanoporous was measured. The acquired results disclosed that target pathogenic microbes in the raw wastewater sample were inactivated when subjected to 100 mg/L of fabricated alumino-copper silicate. Likewise, results could not discover any deleterious and poisonous influences for the Vibrio fischeri bacterium and HEp-2 cell line of such nanostructures subsequently, it will be safe for use in water treatment. This investigation, therefore, recommends that the prepared alumino-copper silicate could be considered a future substitute marvellous and sustained-active disinfectant for the production of pathogenic free treated wastewater for recycling in many different applications.
