Abstract
The invention relates to a preparation method of nano copper oxide. The preparation method comprises the following steps that copper nitrate and sodium hydroxide solids are taken and are respectively dissolved in water; absolute ethyl alcohol is added according to the volume ratio 1:1 of the absolute ethyl alcohol to a copper nitrate solution. The nano copper oxide prepared by adopting the method is simple in process without calcination process, and the operability is strong.
Description
Technical field
The present invention relates to a kind of preparation method of nano cupric oxide.
Background technology
Substantial amounts of foul gass can be produced in city and Industrial Waste Water Treatments factory running, this kind of material is such as without process
Directly discharge can serious harm plant area staff and surrounding resident it is healthy.Sewage treatment plant's purifying low-concentration contains at present
The method of sulfur odorant is mainly bioanalysises and the removal of high-concentration sulfur-containing odorant more and uses metal oxide desulfurizer,
Such as ferrum oxide etc..Consider from thermodynamics, copper oxide has best desulfurized effect.Reported at present based on copper oxide
The desulfurizing agent of composition is wanted to be mainly used in the medium/high desulfuration field of chemical process, such as and in room temperature desulfuration field, copper oxide
It is selected as auxiliary agent collaboration more and completes sweetening process.Copper oxide is less as the research that one-component carries out room temperature desulfurization.Due to
Room temperature composite desulfurizing agent is using the recovery for being unfavorable for useful materials after discarding, and the material after environmental protection requirement is discarded is as far as possible
Reclaim and utilize, therefore the simplification of metal oxide materials increasingly receives publicity, i.e., by the microstructure of change material
To improve the performance of material, wherein nano-desulfurizer can embody this thought very well.Researcher is done in terms of nano-desulfurizer
Substantial amounts of research work, the research of wherein nano zine oxide desulfurizing agent are more deep, and only optimize in terms of nano cupric oxide directly
Process conditions prepared by the sedimentation method.
The content of the invention
The present invention proposes a kind of preparation method of nano cupric oxide.
A kind of preparation method of nano cupric oxide, comprises the following steps：
（1）Copper nitrate and sodium hydrate solid is taken, difference is soluble in water；
（2）It is 1 by dehydrated alcohol and copper nitrate solution volume ratio:1 adds dehydrated alcohol；
（3）Evenly sodium hydroxide solution is slowly added in copper nitrate solution under the precipitation temperature of setting, stirring is certain
Time, ageing, filtration, washing, being close to 7 to the pH value of eluate；
（4）By step（3）Product dries 2-6h at 60-100 DEG C；
（5）Nano cupric oxide is obtained in Muffle kiln roasting 1h.
Preferably, the quality of the copper nitrate solid is 7.3g, and the quality of sodium hydrate solid is 2.8g, by copper nitrate and
Sodium hydroxide grinds 5min respectively, again continues to grind 10 min after then mixing.
Preferably, the step（4）Product heats temperature is 80 DEG C, and drying time is 4h.
Preferably, the step（3）Mixing time is 350rpm, when a length of 2h.
Nano cupric oxide process is simple prepared by the method for the invention, it is not necessary to roasting process, it is workable.
