Abstract

Способ получения наночастиц золота из сырья, содержащего железо и цветные металлы, включающий растворение сырья в царской водке, флотоэкстракцию прекурсоров золота ПАВ, концентрирование и восстановление, отличающийся тем, что сырье вначале растворяют в соляной кислоте, а азотную кислоту перед флотоэкстракцией удаляют метиловым, этиловым спиртом или соляной кислотой.A method of obtaining gold nanoparticles from raw materials containing iron and nonferrous metals, including dissolving raw materials in aqua regia, flotation extraction of gold precursors with surfactants, concentration and reduction, characterized in that the raw materials are first dissolved in hydrochloric acid, and nitric acid is removed before flotation with methyl, ethyl alcohol or hydrochloric acid.
