SURFACE MODIFICATION METHOD OF A NANOSCALE ZERO-VALENT IRON USING CONTROLLED AIR CONTACT AND A SURFACE-MODIFIED NANOSCALE ZERO-VALENT IRON THEREOF

摘要

PURPOSE: A surface modification method of a nanoscale zero-valent iron using controlled air contact is provided to enable mass production through a mass production modification process by forming a shell(iron oxide film).;CONSTITUTION: A surface modification method of a nanoscale zero-valent iron using controlled air contact comprises a step for pre-processing zero-valent iron(10) by contacting air provided from the outside to form a shell(iron oxide film) on the surface of the zero-valent iron. The pre-process comprises a step for washing and drying 100 parts by volume of zero-valent iron slurry with 500-600 parts by volume of acetone.;COPYRIGHT KIPO 2011
