Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in more detail.
The invention discloses the active carbon-point of a kind of nano whisker for filter core, by weight, it comprises the material of following component:
Nano whisker 1 part;
Active carbon 10 ~ 20 parts.
Wherein, described nano whisker is four-needle-shape nano zinc oxide whisker, and its particle size is 10 ~ 100 μm, and described granularity of activated carbon is less than 2.5mm.
In the active carbon-point of above-mentioned nano whisker, nano whisker directly acts on water, thus produces high mars free radical oH, these high mars free radicals have good bacteriostasis, and equation is as follows:
h -+H2O→·OH+H +
Simultaneously, the absorption property of the active carbon-point of this nano whisker is high, can effectively remove chlorine residue in water, peculiar smell, organic matter, in addition, the active carbon-point of this nano whisker discharges without powdered carbon, not breed bacteria, effluent quality microorganism is tending towards " zero bacterium " level, safety non-toxic, the poisonous and harmful substances such as heavy metal free are separated out, and are applicable to all kinds of drink water purifying process.
The present invention also discloses the preparation method of the active carbon-point of a kind of nano whisker for filter core, please refer to following embodiment.
