▎ 摘　　要

NOVELTY - The method involves drying a soil sample for sieving the soil sample through a hundred-meshes sieve to obtain soil powder. The soil powder mixed with ultra-pure water is placed into a vortex oscillator for uniformly mixing the soil powder with the ultra-pure water for about 15 min such that the soil powder is in full contact with the ultra-pure water. A mixture of soil and water is washed in a soil layer table and filtered by a filter film using oxidized graphite alkene at aqueous lower freezing drying temperature of about 50 degrees centigrade to obtain graphene oxide nano material. USE - Method for separating graphene oxide nano material from soil in nano material research application. ADVANTAGE - The method enables simplifying separating process of the graphene oxide nano material from the soil in an easy manner so as to satisfy research requirements of biochemical action in a soil environment. DESCRIPTION OF DRAWING(S) - The drawing shows a photographic view illustrating a method for separating graphene oxide nano material from soil.
