Title:
MAGNETITE AND BIRNESSITE AGGREGATE-FORM MIXTURE, SYNTHESIS METHOD THEREFOR, AND WATER-TREATMENT METHOD USING MIXTURE
Document Type and Number:
WIPO Patent Application WO/2012/165695
Kind Code:
A1
Abstract:
The present invention relates to a magnetite-birnessite mixture, to a synthesis method therefor, and to a water-treatment method using same. The magnetite-birnessite mixture synthesis method according to the present invention comprises: a first synthesis step in which magnetite is synthesised; a second synthesis step in which manganese is made to adsorb onto the surface of the magnetite by supplying manganese while maintaining a basic state in the presence of the magnetite, and then synthesising birnessite on the surface of the magnetite by supplying an oxidising agent and sodium, thereby synthesising a mixture in which magnetite and birnessite are bound together; and a purification step in which the mixture of magnetite and birnessite is purified.
