Abstract
The present invention relates to a kind of sensitive materials for responding hydrogen sulfide and sulfur dioxide simultaneously, it is characterized in that by Al2O3、Dy2O3And Nd2O3The nano-powder material of composition.Preparation method is: aluminium salt, dysprosium salt and neodymium salt are codissolved in aqueous acetic acid, aqueous citric acid solution and isopropanol water solution is added dropwise, sonic oscillation is extremely clarified, it is heated to reflux, then 1/4 moisture is vapored away, cooling obtains gel, and gel infra-red drying, grinding, two-stage roasting, natural cooling are obtained by Al2O3、Dy2O3And Nd2O3The composite powder material of composition.The gas sensor made using sensitive material provided by the present invention, can be more live while measuring the trace hydrogen sulfide in air and sulfur dioxide without by other common interference that molecule coexists.
Description
Technical field
The present invention relates to a kind of sensitive materials for responding hydrogen sulfide and sulfur dioxide simultaneously, especially by Al2O3、Dy2O3With
Nd2O3The sensitive material of nano-powder composition, belongs to field of sensing technologies.
Background technique
Hydrogen sulfide is flammable colourless gas, has typical smell of putrid egg, usually certain chemical reactions and protein are certainly
The product of right decomposable process.The more industry of contact hydrogen sulfide mainly has sewage treatment, papermaking, PETROLEUM PROCESSING, chemical fertilizer manufacture, changes
Learn fiber manufacture and the manufacture of certain industrial chemicals etc..Human body sucking hydrogen sulfide can cause acute poisoning and chronic lesion.It is acute
Hydrogen sulfide poisoning can be divided into three-level, calomel poisoning, moderate intoxication and severe intoxication, different degrees of poisoning, and clinical manifestation has
Apparent difference.Calomel poisoning shows as photophobia, sheds tears, eye shouting pain, foreign body sensation, runny nose, the symptoms such as nose and throat burning heat sensation, inspection
Visible conjunctival congestion, lung's dry rale etc. are looked into, in addition, can also have slight dizzy, headache, symptom out of strength；Moderate intoxication table
Now to occur the symptoms such as giddy, headache, out of strength, Nausea and vomiting, incoordination immediately, there can be the of short duration disturbance of consciousness, while can draw
Respiratory mucosa irritation and Eye irritation symptom are played, checks visible lung's stemness or moist rale, conjunctival congestion, oedema
Deng；Severe intoxication shows as the symptom of apparent central nervous system, and appearance dizziness, palpitaition, expiratory dyspnea, action first is slow
It is blunt, then there is irritated, clouding of consciousness, vomiting, diarrhea, abdominal pain and twitch, quickly enters comatose state, it finally can be because of breathing fiber crops
Numbness and it is dead.When contacting high concentration of H 2 S, " electric shock sample " poisoning can occur, contactee falls down suddenly in a few seconds, exhales
It inhales and stops.The hydrogen sulfide of prolonged and repeated inhalation of low concentration can cause hyposphresia, and neurasthenic syndrome and plant occur
Neurological dysfunction.
Sulfur dioxide is one of major pollutants in atmosphere, is the important symbol measuring atmosphere and whether being polluted.The world
On have many cities that sulfur dioxide harm occurred matters of aggravation, so that many people is poisoned or dead.Sulfur dioxide has acidity,
Small sulphite and sulphate particle can be generated with the substance reaction of other in air.When these particles are inhaled into, it
One of the main reason for being gathered in lung, and being Respiratory symptoms and disease.If mixed with water, then with skin contact,
Just it is likely to occur frostbite.When with eye contact, red and swollen and pain will cause.After sulfur dioxide enters respiratory tract, because its is readily soluble
Yu Shui, therefore major part is arrested in the upper respiratory tract, generating on wet mucous membrane has corrosive sulfurous acid, sulfuric acid and sulfuric acid
Salt enhances stimulation.For the smooth muscle of the upper respiratory tract because there is nerve ending receptor, assassination, which swashs, will generate narrow contracting reaction,
Reduce the lumen of trachea and bronchus, airway resistance increases.The upper respiratory tract acts on this detention of sulfur dioxide, certain
It can reduce stimulation of the sulfur dioxide to lung in degree.Sulfur dioxide can be rapidly absorbed into blood, generate toxic side effect to whole body,
The vigor of its energy destructive enzyme has certain damage to liver to significantly influence the metabolism of carbohydrate and protein.It is dynamic
Object test proves, after sulfur dioxide slow poisoning, the immune of body is obviously inhibited.
Air Hydrogen Sulfide and the accurate detection method of sulfur dioxide mainly have: spectrophotometry, fluorimetry, flowing
The instrument analytical methods such as injected chemical luminescence method, gas chromatography and liquid chromatography.These method sensitivity are relatively high, but
It is complicated for operation, it is necessary to it is completed in laboratory, it can not scene realization.
Summary of the invention
The object of the present invention is to provide a kind of sensitive materials and preparation method thereof for responding hydrogen sulfide and sulfur dioxide simultaneously.
The gas sensor made of this sensitive material, can at the scene quickly, Accurate Determining trace hydrogen sulfide and sulfur dioxide and
