Inorganic salts, formerly called minerals, generally only account for 65,438+0% to 65,438+0.5% of the fresh weight in biological cells. More than 20 species have been found in human body, among which the major elements are Ca, P, K, S, Na, Cl and Mg, and the minor elements are Fe, Zn, Se and Mo.

Sodium is the main component of salt. China Nutrition Society recommended/kloc-The appropriate sodium intake for adults over 0/8 years old is 2.2g per day, and the elderly should eat light food. Sodium is ubiquitous in all kinds of foods. The main sources of human sodium are salt, soy sauce, pickled food, smoked food and salty food.

Other functions of inorganic salts

Inorganic salts can be used as catalysts.

Metal ions contained in inorganic salts, such as copper, iron and chromium, can play a catalytic role in chemical reactions, promote the reaction rate and improve the efficiency and yield of chemical reactions. At the same time, inorganic salts can also be used as catalysts in chemical synthesis to synthesize high value-added chemicals, such as antibiotics.

2. Inorganic salts can be used in electronic industry.

Metal ions in inorganic salts can play an electrocatalytic role in electrochemical reaction and promote electrochemical reaction. Another main application of inorganic salts is as materials in electronic devices, such as electrolytic capacitors, ceramic capacitors and thermoelectric materials.

3. Inorganic salts can also be used to make building materials.

In the construction industry, inorganic salts can be used to make refractories, glass and so on. Inorganic salts can be added to cement, concrete and other building materials to increase their strength and durability. High-purity silicate minerals and oxides for building are important inorganic salt manufacturing materials.
