Overview

This invention relates to a method for the preparation of zero-nanoparticles using phenols and chlorophenols extracted from industrial wastewater as reducing agents . Nanoparticles include iron or silver, bimetallic or bimetallic, for example, silver and iron. One or more phenolic contaminants such as phenol and chlorophenols are first extracted from industrial wastewater. The concentrations of the extracted phenols are then concentrated in an alcohol solution. The iron and silver salts are reduced by phenolic solutions as a reducing agent in a base medium under microwave radiation to obtain iron, silver or iron / zero silver metals. The prepared nanoparticles are characterized by their almost symmetrical crystalline forms, with an average size of 82 nm and silver 22 nm. The nano-silver / 62 nm mixture is used to remove aromatic organic pollutants and antimicrobials.
