NOVELTY - A nano mineral purified particles comprise 50-70 pts. wt. sepiolite, 0.1-0.5 pt. wt. graphene, 5-10 pts. wt. attapulgite, 10-20 pts. wt. activated carbon powder, 5-10 pts. wt. kieselguhr, 10-15 pts. wt. bentonite, and 3-5 pts. wt. anion powder. USE - Nano mineral purified particles. ADVANTAGE - The product ensures pure natural product, absorbs formaldehyde and harmful gas including formaldehyde, benzene, total volatile organic components, and decomposes, removes and releases anion. The method is mature, and has simple steps. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of nano mineral purified particles comprising sieving materials by 200 mesh, uniformly stirring and mixing to obtain mixed powder, adding aluminum sulfate solution, uniformly stirring, granulating into ball, low temperature drying into furnace at 180-260 degrees C for 1-2 hours, putting into high temperature activation furnace, and activating at 600-780 degrees C for 1 hour.
