▎ 摘　　要

NOVELTY - Synthesis of photocatalytic nanocomposite material involves (a) synthesizing lanthanum orthoferrite nanostructure materials via solgel method to obtain lanthanum orthoferrite nanostructure materials, (b) calcining the lanthanum orthoferrite nanostructure materials to obtain a calcined lanthanum orthoferrite nanostructure materials, (c) adding graphene oxide in the calcined lanthanum orthoferrite nanostructure materials to obtain a suspension mixture, (d) mixing the suspension mixture with magnetic stirrer for 24 hours at room temperature to obtain a homogeneous solution, and (e) centrifuging and filtering the homogeneous solution using ethanol and dried at 65 degrees C for 8 hours to obtain lanthanum orthoferrite/graphene oxide powder. USE - Synthesis of photocatalytic nanocomposite material used in wastewater treatment, and removal of pharmaceutical emerging contaminants from clinical waste. ADVANTAGE - The method enables synthesis of photocatalytic nanocomposite material having excellent photocatalytic activity and adsorption property for application in wastewater treatment, preferably removal of emerging contaminants. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart of the synthesis of the photocatalytic nanocomposite material.
