First, from the price to identify: Where the market 200 grams, 400 grams / bag, write the words potassium dihydrogen phosphate products, pesticide store retail price of about 2 yuan, can be determined as fake potassium dihydrogen phosphate. The vast majority of the content is zero, and some products exceed the maximum of 15%, because the real 400Kg of potassium dihydrogen phosphate raw materials is much higher than 2 yuan, not to mention the finished product, and the low price is not the manufacturer's profit.
Second, from the taste to identify: buy potassium dihydrogen phosphate to open to take a few taste, bitter taste is fake potassium dihydrogen phosphate, may be magnesium sulfate or chemical industry waste salt. It may be true that it is salty, but it is very salty. The bitter, bitter taste of sea salt may be similar to that of sea salt. It is also counterfeit. The real potassium dihydrogen phosphate is a faint salty taste. Potassium dihydrogen phosphate that can smell (odor, ammonia) is false, because the real potassium dihydrogen phosphate is a white, odorless crystal.
Third, identify from the packaging:
(1) Potassium dihydrogen phosphate should be marked on the packaging and there should be detailed factory name, address, telephone number, and implementation standard number. Others such as those labeled as complex, modified, potassium dihydrogen phosphate, etc. are not genuine.
(2) The word potassium dihydrogen phosphate is written in very large letters, and the ammonium word is very small; the small-character compound fertilizer (II) is marked on the upper right of the packaging bag, and the potassium dihydrogen phosphate is marked in the middle; Potassium dihydrogen phosphate type II. All are deceiving people.
(3) In the description, it is indicated that the product consists of nitrogen, phosphorus and potassium, and even trace elements such as boron, zinc, iron, regulators (hormones), growth factors, rare earths and other high-tech nouns are fake and cheating. Farmers' friends. As we all know, 98% of potassium dihydrogen phosphate only contains phosphorus, potassium, and does not contain nitrogen, trace elements, etc., the national standard also does not have I, II type, compound of the points, so the composition content of nitrogen, phosphorus, potassium compound, containing Trace elements, rare earths, and complex potassium dihydrogen phosphate can all be considered as fakes.
(4) The bottled liquid potassium dihydrogen phosphate is circulated on the market. It does not conform to the appearance of white crystal or powder on the standard of HG2321-92, and according to the relevant regulations of the country, there is no liquid potassium dihydrogen phosphate product. More inconsistent with the fertilizer registration requirements of the Ministry of Agriculture of the People's Republic of China, production is not allowed and it can be regarded as fake goods.
(5) The packaging is simple, rough, the name of the plant, the site is unknown, the name of the plant is used fraudulently, the telephone can't work, and the terms such as pure product, high-purity import, genuine product, compound, nanometer, etc. are all regarded as fake products.
Fourth, technology identification:
(1) Take a little heat on a piece of iron to dissolve it into a transparent liquid. After cooling, it is solidified into a translucent glassy substance. If the appearance of white crystals or powder, take a small amount of exposure in the sun, the traits and color does not change the basic can be considered authentic, such as changes are doubtful.
(2) Take one glass, warm up to half a cup, add 50 grams of soda ash to the water, and stir until the soda ash is completely dissolved. Take 10 grams of potassium dihydrogen phosphate and add it to the soda ash solution. If there are a lot of bubbles, it is genuine. If there is a lot of flocculent precipitation or other reactions, it means that they are fake and shoddy products.
(3) If you use fire, if you have a taste of nitrogen, it is a counterfeit product because the genuine product does not contain nitrogen.
(4) The addition of zinc sulfate and ferrous sulfate to the aqueous solution of potassium dihydrogen phosphate will produce a precipitate. If the use of magnesium sulfate is falsified, the aqueous solution will not precipitate after adding zinc sulfate and ferrous sulfate.
Fifth, when buying potassium dihydrogen phosphate to the agricultural resources to ask for valid evidence, find the relevant agricultural technology department to identify or test, one to distinguish the authenticity.
