Abstract
The invention discloses a deodorant capable of removing hydrogen sulfide. The deodorant comprises the following substances by mass: 30 to 40 parts of ferrous sulfate, 50 to 70 parts of industrial hydrochloric acid, 20 to 30 parts of tartaric acid, 10 to 15 parts of humic acid, 1 to 5 parts of cyclodextrin and a proper amount of deionized water amount. The deodorant provided by the invention is capable of effectively removing hydrogen sulfide in stink; a preparation method for the deodorant is simple and enables considerable manpower and material resources to be saved; and the deodorant exerts good deodorizing effect.
Description
Technical field
The present invention relates to a kind of deodorizer, particularly relate to a kind of deodorizer removing hydrogen sulfide, belong to technical field of chemistry and chemical engineering.
Background technology
Stench, as one of atmospheric pollution public hazards, is subject to the extensive attention of various countries in the world.And abroad some country just starts the research of this aspect earlier, in June, 1971, first Japan carry out special project legislation to stench.Sense of smell is because volatile molecules and stink substance interact, and stimulates the mammals such as people to be positioned at the sensorineural result of nasal cavity top olfactory sensation.Feeling of abnormal smells from the patient is very complicated, and it affects by psychological factor, meteorological factor, subjective sensation, inherited genetic factors etc.About 10,000 kinds are had to the material of mankind's foul smelling olfactory stimulation, determine odor pollution material in 8 in China's " emission standard for odor pollutants ", they are hydrogen sulfide, methanthiol, methane thial, methyl disulfide, my carbon dioxide, ammonia, trimethylamine, styrene respectively.Wherein, five kinds of pollutant sulfurous gas are had.
Hydrogen sulfide has rotten egg abnormal smells from the patient and goes out gas, and during low concentration, it can cause ophthalmia, eye portion secretions, corneal opacity photophobia, and bronchitis, the even pharyngeal edema of cough have occurred; Can cause that human body qualitative change is weak as inhaled hydrogen sulfide for a long time, resistance declines, enteritis easily occur, has a weak heart, neurological disorders, multifocal neurological inflammation etc.
Residential block is safeguarded just gradually in some domestic garbage loading embeading places, and landfill yard causes odor pollution scope generally in the interval of 2.0km, and stench scope can reach more than 6.0km under disadvantageous inversion condition.I.The survey showed that in China 329 urban garbage disposal fields, and main gases containing stench sulphureous gases is H2S, and in the uncontrollable discharge waste gas of each landfill yard, the exceeding standard rate of H2S is 7.6%, and times of ultra standard is 0.5 ~ 24 [6].In order to be familiar with the transportion and transformation of hydrogen sulfide further, and finally reaching the object controlling garbage sanitary filling field foul gas, studying it becomes current environmental area important topic in the generation of landfill yard and change mechanism.
Summary of the invention
The present invention relates to a kind of have for the hydrogen sulfide in foul smell, there is effective removal effect, preparation method is simple, plays the deodorizer that good deodorizing effect removes hydrogen sulfide.
Remove a deodorizer for hydrogen sulfide, by mass parts, comprise following material: 30 ~ 40 parts, ferrous sulfate, technical hydrochloric acid 50 ~ 70 parts, 20 ~ 30 parts, tartaric acid, humic acid 10 ~ 15 parts, cyclodextrin 1 ~ 5 part, deionized water is appropriate.
Preferably, a kind of deodorizer removing hydrogen sulfide, by mass parts, comprises following material: 32 ~ 38 parts, ferrous sulfate, technical hydrochloric acid 55 ~ 65 parts, 21 ~ 29 parts, tartaric acid, humic acid 11 ~ 14 parts, and cyclodextrin 2 ~ 5 parts, deionized water is appropriate.
The mass fraction of described technical hydrochloric acid is 36 ~ 40%.
Removing a deodorizer for hydrogen sulfide, is obtained by following steps:
(1) ferrous sulfate technical hydrochloric acid, tartaric acid, humic acid are dissolved, stir, remove insoluble matter;
(2) by cyclodextrin deionized water dissolving, stir, remove insoluble matter;
(3) dextrin in aqueous solution is added in (1) solution, stir.
Deodorizer of the present invention has effective removal effect for the hydrogen sulfide in foul smell, and its preparation method is simple, saves a large amount of manpower and materials, plays good deodorizing effect.
Detailed description of the invention
Embodiment 1:
Remove a deodorizer for hydrogen sulfide, by mass parts, comprise following material:
Deionized water is appropriate.
This deodorizer is prepared by following methods:
(1) ferrous sulfate technical hydrochloric acid, tartaric acid, humic acid are dissolved, stir, remove insoluble matter;
(2) by cyclodextrin deionized water dissolving, stir, remove insoluble matter;
(3) dextrin in aqueous solution is added in (1) solution, stir.
This deodorizer has effective removal effect for the hydrogen sulfide in foul smell.
Embodiment 2:
Remove a deodorizer for hydrogen sulfide, by mass parts, comprise following material:
Deionized water is appropriate.
Its preparation method is with embodiment 1.
This deodorizer has effective removal effect for the hydrogen sulfide in foul smell.
Deodorizer of the present invention has effective removal effect for the hydrogen sulfide in foul smell, its preparation method is simple, save a large amount of manpower and materials, play good deodorizing effect, therefore, be mainly used in the removal to hydrogen sulfide in foul smell, not producing other harmful gass is a kind of environmentally friendly deodorizer.
Invention can be understood further by the invention process given above; above embodiment is only several specific embodiment of the present invention; but design concept of the present invention is not limited thereto; all changes utilizing this design the present invention to be carried out to unsubstantiality, all should belong to the behavior of invading scope.
