Abstract
The invention discloses a device for quickly detecting the arsenic in sample, comprising an arsenic generating bottle, an arsenic reacting chamber, a buffer tube, an arsenic filter pulp, arsenic developing test paper and an arsenic fast testing color-order card. The top of the arsenic reacting chamber is communicated with the buffer tube and the bottom of the arsenic reacting chamber is communicated with the arsenic generating bottle. During detecting, the color variation of the arsenic developing test paper after chemical reaction is observed by combining the arsenic fast testing color-order card, therefore the presence and content of the arsenic in sample can be judged. The invention can be used for quickly detecting the content of the arsenic in situ in sample: water, foodstuff, cosmetic, electronic product, metallurgy, sulphuric acid, fertilizer, leather, pesticide and vegetable, fruit, meat and meat products, water products, bean products, eggs, cakes and so on.
Description
Technical field
The present invention relates to the device of arsenic in a kind of fast detecting sample, be specifically related to a kind of device that is used for other sample arsenic content such as field quick detection water quality, food, cosmetics, electronic product, metallurgy, sulfuric acid, chemical fertilizer, leather, agricultural chemicals and vegetables, fruit, meat and meat products, aquatic products, bean product, eggs, cake.
Background technology
Along with the progress of human society and the raising of economic level, environmental protection problem more and more receives the concern of national governments, international organization, industry organization, industry specialists and even general public.How the testing environment pollution problem obtains the great attention of each relevant departments too.Wherein, in numerous environmental pollutions, arsenic is huge to people's healthy threat, has become the stealthy killer of human body health.So, the detection of heavy metal arsenic has been become the task of top priority.
Arsenic is an ancient poisonous substance.The soluble compound of arsenic and arsenic all is toxic articles.As arsenic (white arsenic) is exactly arsenic trioxide.Arsenic mainly exists with compound or simple substance at occurring in nature, and arsenical pyrite (FeAsS), realgar (As2S are arranged
2), orpiment (As2S
3).Contain arsenide in many nonferrous metallic ores, so in nonferrous metallurgical process (as the ore roast), all have arsenide (as white arsenic) to discharge.Burning of coal contains arsenic in the coal and on average can reach 25 milligrams/kilogram, so can make the arsenic concentration of surrounding air reach 0.02 microgram/cubic meter.Arsenide is used for making the hair remover and the antiseptic of wimet (as adding 35% arsenic in the plumb), arsenate medicine, pesticide, rat poison (being generally arsenic acid, arsenious acid salt), glass industry decolorant, fur industry more.So industry such as metallurgy, sulfuric acid, chemical fertilizer, leather, agricultural chemicals all have arsenic contamination.Problem arsenic can enter human body by approach such as breathing, skin contact, diet.Arsenic can combine with the sulfydryl in protein and the enzyme, suppresses a lot of biochemical processes in the body, particularly combines with the sulfydryl of pyruvate oxidase, and it is lost activity, and causes the serious disorder of cellular metabolism.Arsenic is 0.01～0.052 gram to people's toxic dose, and lethal quantity is 0.06～0.2 gram.The acute poisoning symptom of arsenic is: throat, esophagus and stomach and intestine burn feeling, diarrhoea, stomachache, headache, feel sick, vomiting, mouthful drink, facial cyanosis, blood pressure reduce death rapidly when being in a bad way rapidly.The arsenic poisoning effect also is an accumulation property, can accumulate in osteoporosis portion, kidney,liver,spleen, muscle and keratinized tissue (as hair, skin and nail).Find also that in recent years in workman that matter containing arsenic often contacts, the incidence of disease of cutaneum carcinoma and lung cancer is higher than other industry; And skin ulcer, perforation of nasal septum are more common.
Arsenic content must not surpass 10 mg/kg in the cosmetics.Otherwise can cause poisoning.
At present, usually use the comprehensive instrument that is placed in the laboratory that arsenic is detected, Shang Weijian can be applicable to the report of the device of arsenic in the on-the-spot fast detecting sample, and above-mentioned heavy metal arsenic has had a strong impact on people's normal life to the pollution of environment, the existence that can field quick detection goes out these objectionable impuritiess is very necessary, and the device of arsenic provides a kind of means of field quick detection in the fast detecting sample of the present invention.
