▎ 摘　　要

NOVELTY - A non-metallic nanoparticle is synthesized using cereal and pulse washed wastewater by treating non-metal oxide/borides with reducing agent, cereals or pulse washed water at predetermined reaction condition to form the non-metallic nanoparticle. USE - Synthesis of non-metallic nanoparticle e.g., reduced graphene oxide and borophene nanoparticle (all claimed). ADVANTAGE - The method carries out effective utilization of wastewater successfully. The nanoparticle has the potential to kill clinical pathogens. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) synthesizing reduced graphene oxide nanoparticle using cereal or pulse washed wastewater which involves refluxing 150 mL reducing agent, raw Oryza sativa washed wastewater with 100 mL graphene oxide for 6 hours at 80-90 degrees C to form the reduced graphene oxide nanoparticle; and (2) synthesizing borophene nanoparticle using cereal or pulse washed waste water which involves (a) sonicating 50 mg magnesium boride in 50 ml HPLC grade water for 1 hour and allowing to stand undisturbed for one day to form a solution; (b) centrifugating the solution to obtain a centrifugate where residue is discarded; and (c) treating 50 mL centrifugate with 50 ml characterized reducing agent, Pennisetum glaucum washed wastewater followed by mixing in probe sonicator for 1 hour to form the borophene nanoparticle.
