METHOD OF EXTRACTION OF HEAVY METAL IONS FROM THE SOLID MATERIALS Russian patent published in 1996 - IPC

Abstract RU 2057812 C1

FIELD: industrial ecology. SUBSTANCE: microorganism biomass is treated with excess of hydrolyzing reagent aqueous solution and solid and liquid phases were separated. Solid material is extracted with liquid phase. Heavy metal ions were sorbed with the solid phase from the liquid phase after extraction. EFFECT: improved method of extraction.
