The fast detection kit comprises a suction tube, a colorimeter tube, a device containing a color-developing agent, a vessel and a standard color palette, wherein the vessel is provided with scales and can be sealed; the color-developing agent is a substance containing ferrocyanide ions; a standard colorimeter slot can be arranged on the standard color palette; and contrast color is coated in the standard colorimeter slot or different red brown ferrocyanide copper solutions are poured into the standard colorimeter slot.
Description
Technical field
The utility model relates to a kind of quick detection kit, is specifically related to the quick detection kit of copper ion in a kind of food, is mainly used in the fast detecting to content of copper ion in the consumable products such as fruits and vegetables, beverage, water.
Background technology
Chlorophyll is a kind of natural colouring matter, and is relatively more responsive to light, heat, soda acid etc., normal fugitive color or variable color in the process of processing and storage.The coloring agent price that is used to bleaching and dyeing pollution-free food in the food additives is higher, and Color is not obvious, the price of every bottle 500 gram of common coloring agent about 50 yuan, quality high dyeing agent price even up to hundreds of unit.
Therefore, some illegal retailers strengthen sensory effects for the long-term green that keeps fruits and vegetables, cover low-quality goods, reduce cost, come the substitute food product adjuvant, as copper sulphate, stannous chloride, cupric chloride, cupric pyrophosphate, cuprous oxide, Schweinfurt green, copper carbonate etc. with mantoquita.
As everyone knows, copper sulphate is mainly used in fuel and pigment, pesticide, antiseptic, fabric mordant and beneficiation reagent etc. in inorganic industry, and the price of industrial sulphuric acid copper is 10 yuan/kilogram.The copper sulphate of excess intake can produce the look intense stimulus to human gastrointestinal tract, may cause nausea, vomit, mouthful in copper nature and flavor, heart-burn sense etc. are arranged; Severe patient may cause gastric colic, spitting blood, melena, hemoglobinuria, acute renal failure; Long-term contact can come in contact dermatitis and nose, eye stimulate, and gastrointestinal symptom occurs; Simultaneously,, cause the metabolic disturbance in the human body, symptoms such as cirrhosis and hepatic ascites occur when heavy metals such as the remaining a large amount of copper of human body very easily cause burden to internal organs.
The proposed standard of the World Health Organization (WHO) and grain farmer management committee is: man's average copper intake is no more than 12 milligrams/day, and woman's average copper intake is no more than 10 milligrams/day.And finding that in product investigation its copper content is up to 120 milligrams/kilogram-1200 milligrams/kilogram to illegal retailer, the consumer will produce huge threat to health when eating this series products.
At present, the method of measuring copper both at home and abroad in the food has atomic absorption method and extraction colorimetry, but above-mentioned two kinds of methods are to being applied to the laboratory or the professional detects, ordinary consumer is difficult to be suitable for, therefore, be badly in need of a kind of suitable family expenses, and be easy to carry, quick, easy, the cheap product that can detect copper content in the fruit-vegetable food.
Summary of the invention
The utility model to be to provide the quick detection kit of copper ion in a kind of food, and mainly having solved does not have the family expenses of being fit in the background technology, and be easy to carry, quick, easy, the cheap product that can detect copper content in the food such as fruits and vegetables.

Fig. 2 has the Standard colour board structural representation of standard cell for quick detection kit;
Fig. 3 has another Standard colour board structural representation of standard cell for quick detection kit;
Fig. 4 a is a quick detection kit color comparison tube structural representation;
Fig. 4 b is another structural representation of quick detection kit color comparison tube.
Embodiment
The utility model mainly is to contain the solution and the determinand reaction of ferrocyanide ion, and its principle is that ferrocyanide ion and copper ion reaction back generate the copper ferrocyanide red-brown precipitation, is example with the potassium ferrocyanide, and its chemical equation is:
K
4[Fe(CN)
6]+2CuSO
4＝Cu
2[Fe(CN)
6]↓+2K
2SO
