NOVELTY - This utility new type claims a one filter, include the shell and filter core, filter core inner packaging the shell; one end a shell set with a water inlet, and the other end set with the water outlet, water from water inlet entering into the water inlet, the filter core, a water outlet, a filter core is graphene molding of graphene filter core. This utility new type universal using graphene filter core, the graphite alkene of efficient absorption and graphene oxide surface can produce a large amount of hydroxyl, carboxyl and epoxy radical, the oxygen-containing group for metal ion has great affinity of, so it can well absorbing of metal ion in water.
