Description
Technical field
The invention belongs to water purifier technical fields, and in particular to a kind of preparation method of graphene filter element of water purifier.
Background technology
Along with the fast development of social economy, water environment pollution and shortage of water resources problem become increasingly conspicuous, heavy metal by
It is high, not degradable and be easily enriched in vivo in its toxicity, become the important pollutant in water pollution；Water hygiene
Event happens occasionally, and particularly heavy metal ion pollutes, and seriously affects health, therefore the safety and sanitation of drinking water have caused
The great attention of various circles of society；General purifier purification style is single, be only capable of solving to a certain extent the coloration of water,
The slight pollutions such as turbidity, it is poor to the removal effect of heavy metal ion.
Invention content
In order to compensate for the shortcomings of the prior art, the present invention provides a kind of preparation methods of graphene filter element of water purifier.
The present invention is achieved through the following technical solutions：

For graphene oxide filter cylinder, be equipped with filter core layer in filter cylinder, the filter core layer include active carbon layer, concave convex rod soil layer, manganese rock layers and
Trivalent chromium rock layers.
Further, the preparation method of the graphene water purification catridge, comprises the following steps that：
（a）Prepare graphene oxide, using the potassium permanganate in the concentrated sulfuric acid with powdered graphite is oxidized react after, obtain brown
Have derivative carboxylic acid group at edge and be mainly the graphite flake of phenolic hydroxyl group and epoxy group in the plane, this graphene layers warp
Ultrasound or high shear are vigorously stirred stripping as graphene oxide,
（b）Graphene oxide filter cylinder is prepared, by graphene oxide powder and polypropylene powder according to 6:1 mass ratio uniformly mixes
Chimney filter mold is packed into after conjunction；Then by the chimney filter mold, gradually heating reaches 200 DEG C or so；In 10~30MPa of pressure limit
Under graphene oxide filter cylinder is made to chimney filter 15~30min of mould pressurizing, cooling and demolding；
（c）Graphene filter element of water purifier is prepared, fills filter core layer in graphene oxide filter cylinder hollow space, filter core layer is from top to bottom
Active carbon layer, concave convex rod soil layer, manganese rock layers and trivalent chromium rock layers are followed successively by, had both obtained graphene oxide water purification catridge.
The beneficial effects of the invention are as follows：A kind of preparation method of graphene filter element of water purifier of present invention filter cylinder therein uses
Graphene oxide is raw material, significantly enhances the removal ability to harmful substance in water, and adsorptivity is stronger；It inhibits bacteria etc. micro-
The growth of biology；Simple in structure light and handy, purifying water effect is good, and service life is long；It is net including tap suitable for Household water purification equipment
The purifiers such as hydrophone, purifying kettle.
