NOVELTY - A graphene oxide water filter cartridge is prepared by performing chemical oxidation to obtain graphite oxide slurry, adding ice water mixture to dilute, uniformly stirring, adding hydrogen peroxide solution to remove residual oxidant, completely reacting, washing, drying to obtain graphene oxide, uniformly mixing graphene oxide powder and polypropylene powder with mass ratio of 6:1 into filter tube mold, gradually warming at 200 degrees C, press molding for 15-30 minutes under 10-30 MPa pressure, cooling, demolding to obtain graphene oxide filter tube, and partially filling with copper-zinc alloy. USE - Preparation of graphene oxide water filter cartridge for household water purification device, such as tap water purifier and bottled water purifier. ADVANTAGE - Preparation process is simple, and product has effectively filtered heavy metal ion in water, inhibited growth of bacteria, good water purification effect, long useful life, and simple structure. DETAILED DESCRIPTION - A graphene oxide water filter cartridge is prepared by performing chemical oxidation to obtain graphite oxide slurry, adding ice water mixture to dilute, uniformly stirring, adding hydrogen peroxide solution to remove residual oxidant, completely reacting, washing, drying to obtain graphene oxide, uniformly mixing graphene oxide powder and polypropylene powder with mass ratio of 6:1 into filter tube mold, gradually warming at 200 degrees C, press molding for 15-30 minutes under 10-30 MPa pressure, cooling, demolding to obtain graphene oxide filter tube, partially filling with high purity copper-zinc alloy, forming core layer, and laying nonwoven fabric protective layer in which graphene oxide water filter cartridge comprises filter tube which is filled with filter layer, outer surface of filter tube is surrounded with protective layer, protective layer is nonwoven fabric, and filter layer is high purity copper-zinc alloy.
