Sodium tripolyphosphate is an inorganic compound with a chemical formula of NaP﹤ O, which is an amorphous water-soluble linear polyphosphate. It is widely used in many fields. In the food industry, sodium tripolyphosphate is often used as a water retention agent, quality improver, pH regulator and metal chelating agent. It can be used in products such as canned food, juice drinks, dairy products and soy milk to improve the quality and taste of the products.

Industrial yellow phosphorus

Industrial yellow phosphorus, also known as white phosphorus, is an important industrial raw material, widely used in chemical fertilizers, pesticides and other fields. It can be produced by the electric furnace method, that is, phosphate rock, silica and coke (or white coal) are put into an electric furnace in a certain proportion and heated to 1300-1500 degrees Celsius for reaction.

What is the role of phosphoric acid in the production of activated carbon?

Phosphoric acid activated carbon with husk as raw material, H3PO4 as activator to prepare can be used for citric acid, monosodium glutamate, lactic acid, xylose and other products production decolorization of activated carbon. The effects of immersion time, liquid-solid ratio, H3PO4 concentration, reaction activation time and temperature on product yield, methylene blue decolorization and caramel decolorization were studied. The yield, methylene blue decolorization and caramel decolorization of activated carbon prepared at room temperature (25 ℃) for 3 d, liquid-solid mass ratio of 2.5 ∶ 1, H3PO4 mass fraction of 65%, activation temperature and time of 550 ℃ and 1 h, respectively, were 46% 1, 3 mL and 100, respectively. Activated carbon is widely used in chemical industry, medicine, food, light industry, environmental protection, water treatment and other fields because of its developed pores and huge specific surface area.
