A NATURAL BIOMASS SILICA NANOPOWDER HAVING A HIGH POLLUTANT REMOVAL PERFORMANCE, EXTRACTED FROM CORN COB PELLET AND A METHOD OF MANUFACTURING THE SAME

摘要

PURPOSE: A natural biomass silica nanopowder with an excellent contaminant removal ability extracted from a cornstalk pellet and a manufacturing method thereof are provided to selectively manufacture an amorphous silica, which is a highly graded silica, by controlling pH, and a mineral silica can be replaced as a corn stalk is recycled as a biomass resource. CONSTITUTION: A manufacturing method of a natural biomass silica nanopowder with an excellent contaminant removal ability extracted from a cornstalk pellet comprises steps of: pre-processing a cornstalk pellet ash to remove minerals other than silica, extracting the silica by controlling pH to be 6 to 11 in an aqueous solution including the pre-processed silicon, and obtaining a silica nanopowder by centrifuging and drying the extracted silica.
