资源简介：
This invention refers to a method for producing magnetic cork particles comprising the steps of providing a composition of an alkaline solution and cork particles， with a size comprised between 1 nm and 2 mm， and stirring; Adding an acid solution containing Fe 3+ and Fe2+ cations to the composition to cause the magnetization of the cork particles and maintaining the stirring; Filtering the solution obtained to obtain a magnetized cork particles precipitate， and washing the precipitate with water until the washed solution reaches a pH comprised between 4 and 7， and let dry until obtaining stabilized magnetized cork particles， wherein the magnetization of the cork particles is due to the formation of a magnetite coating on the particles， being the magnetite adsorbed on the particle surface. It also refers to magnetized cork particles thus obtained and their uses.
