Abstract: Title: Method for synthesizing copper micropowder from E-waste Disclosed is a method (100) for synthesizing copper micropowder from copper recovered from e-waste, includes pre-treating (102) the copper by cleaning and mechanically reducing 5 size into smaller pieces or strands, oxidizing (104) the copper into copper acetate monohydrate by reacting it with glacial acetic acid and hydrogen peroxide, wherein hydrogen peroxide is added gradually to control the reaction, concentrating and drying (106) the oxidized product to obtain copper acetate monohydrate, dissolving (108) the copper acetate monohydrate in deionized water to form a 0.1 M aqueous solution, heating (110) the aqueous 10 solution to 60-100°C, adding (112) the heated solution to an equal volume of 1 M L-ascorbic acid solution, stopping (114) the stirring when turns dark brown, indicating the formation of copper micropowder; and filtering (116), washing with distilled water and ethanol, and drying the copper micropowder. Figure 1 will be the reference.
