▎ 摘　　要

NOVELTY - Portable graphene oxide microfiltration membrane water purification bottle comprises a water purification bottle. The water purification bottle is provided with a bottle cap (2). The water purification bottle is made up of soft plastic. The water purification bottle is detachably provided with a filter element. The upper end of the filter element is adapted to the bottle port of the water purification bottle. The filter element comprises a mesh (6). The mesh is filled with a graphene oxide microfiltration membrane wire (5). The water channel is formed between the mesh, graphene oxide microfiltration membrane wire, and water bottle port. USE - Used as portable graphene oxide microfiltration membrane water purification bottle. ADVANTAGE - The bottle: has simple structure and convenient operation; and removes harmful substance and heavy metal ion in water source. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the filter element system of water purification bottle.
