Description
Technical field
The utility model relates to a kind of medical detecting Instrument, is specifically related to a kind of hydrogen peroxide pick-up unit.
Background technology
Hydrogen peroxide (H
2O
2), the popular name hydrogen peroxide is a kind of colourless liquid that strong corrosion is arranged, its aqueous solution is widely used as sanitizer, germifuge, bleaching agent, deodorant etc. owing to have oxidation, effect such as anticorrosion in fields such as medicine, food, chemical industry, environmental protection.
Because hydrogen peroxide has cheap price, good antiseptic effect to keep characteristic such as food good appearance, some illegal manufacturers consider for commercial interest, in the production of some food, process, soak excess hydrogen peroxide in violation of rules and regulations, as: 1. water is sent out product such as water is sent out broad bean, Omasum etc., and aquatic products such as jellyfish, shark's fin, peeled shrimp, hairtail etc. are used for bleaching; 2. be used for the nut bleaching, the color of shell of walnut, almond is shoaled; 3. be used for sterilization, anticorrosion in fruit, the canned vegetables; 4. be used to improve product appearance in Flour product such as bread, the biscuit; 5. be used for protein composition improvement in starch, whey and the milk.In addition, investigation also find minority food processing unit with mouldy aquatic products dry product through soaking hydrogen peroxide and handle that bleaching is sold again or for eliminating blackout, extravasated blood and the mildew on die of illness chicken, duck or pork surface, with these raw material soaking high concentration hydrogen peroxide bleachings, add artificial color or nitrite chromogenic again and sell.
Yet, in the food production process, use excessive hydrogen peroxide will lead the final products residual peroxide according to the method described above, and residual peroxide is too high in the food, can cause following grievous injury to human body: 1. can cause human genetic material dna damage and gene mutation, with being related closely of various pathologies, long-term edible dangerous huge; 2. can cause animals such as mouse and rabbit carcinogenic, thereby may have carcinogenic danger the mankind; 3. may quicken the senescence process of human body, the generation of hydrogen peroxide and senile dementia, especially alzheimer's disease or develop in close relations; 4. closely related with the development of old Parkinson's disease, headstroke, artery sclerosis and nephrosis and diabetic neuropathic pathology; 5. pass through polyphenoils in the consume body as strong oxidizer, make antioxidant ability of organism low, resistibility descends, and further causes various diseases; 6. may cause or increase the weight of eye diseases such as cataract; 7. enter by respiratory tract and can cause injury of lungs; 8. repeatedly contact can cause human hair, comprises that hair bleaches, cholesteroderma etc.; But 9. eat sticking the touching of stimulating gastrointestinal and cause injury of gastrointestinal tract and enterogastric diseases; 10. micromolecule hydrogen peroxide per os is easy to enter in-vivo tissue and cell after taking in, but freedom of entry radical reaction chain causes the numerous disease relevant with free radical.
Therefore, FAO (Food and Agricultural Organization of the United Nations) and WHO (World Health Organization) are according to its toxicity test report regulation, and hydrogen peroxide only limits to the usefulness of milk corrosion-resistant emergency measures.The also regulation hydrogen peroxide use of in milk, limiting the quantity of only of China's " food additives use hygienic standard ", and only limit to the Inner Mongol and two places, Heilungkiang, in other food, all must not have residual.
At present, in food service industry the abuse of hydrogen peroxide or residual be a serious problem, serious harm people healthy, therefore press for a kind of fast, simple and sensitive hydrogen peroxide pick-up unit of development.
On the other hand, at industrial circle, hydrogen peroxide is used to water treatment procedure more and more widely, particularly in the advanced oxidation water treatment, therefore, how to measure concentration of hydrogen peroxide continuously and automatically, the dosage of control hydrogen peroxide, still all quite important economically technically.The liquid that contains hydrogen peroxide simultaneously in the industrial process is discharged in the environment, can cause environmental water systems to pollute, so the detection of concentration of hydrogen peroxide also is an important indicator of environmental protection tests.
At present, the method that detects content of hydrogen peroxide is a lot, and known main prior art is as follows: conventional titrimetry, spectrophotometric method, fluorescence spectrophotometry, chemoluminescence method, electrochemical process and chromatography etc.Wherein, use special Laboratory Instruments measuring apparatus hydrogen peroxide such as spectrophotometer, often cause testing result higher because of the existence that reducing substances (as vitamin C etc.) is arranged in the food.Adopt the HPLC method to detect, then need to adopt large-scale precision instrument, and the complex pretreatment of sample, detection time is long.The employing electrochemical method detects, though have very high sensitivity, because the modification of enzyme electrode and testing conditions limit, can cause the poor stability of electrode, is difficult for preserving.And additive method is also all more loaded down with trivial details from running program, and is consuming time all longer, the detection place of specialty such as generally is applicable in the laboratory.Therefore.Develop a kind ofly be easy to carry, simple to operate, cheap, and the hydrogen peroxide pick-up unit of execute-in-place is necessary at any time.
