Principle of sodium citrate anticoagulation

Sodium citrate (sodium citrate) can be used as anticoagulant and blood transfusion agent, preservation and processing of blood products by utilizing the property that citrate root and calcium ion can form soluble complex.

Sodium citrate is used as a flavor agent and stabilizer in the food and beverage industry; it is used as an anticoagulant, phlegm remover and diuretic in the pharmaceutical industry; it can be used as an auxiliary of non-toxic detergent in the detergent industry instead of sodium tripolyphosphate; it is an excellent chelating agent/complexant in the chemistry and its application in the industry makes use of this characteristic. It is also used in brewing, injection solution, photographic drugs and electroplating.

Sodium ninhydrin is used as a preservative to preserve medicines such as syrups. Sodium citrate when injected and potassium salts, as used to correct the acidity of blood, body fluids and urine, as a diuretic, phlegm agent, etc.. Sodium citrate with other reagents can be used to extract, purify animal liver ribonucleic acid.

Expanded Information

Sodium citrate has good water solubility, excellent chelating ability for Ca2+, Mg2+ and other metal ions in water, biodegradation, dispersing ability and strong resistance to redeposition, etc. Therefore, it is gradually becoming an alternative to sodium tripolyphosphate, and it is used to produce phosphorus-free laundry detergents, especially phosphorus-free liquid detergents. Adding a certain amount of sodium citrate to detergents can significantly increase the detergency of detergents.

The extensive use of sodium tripolyphosphate as a detergent booster in detergents is an important discovery in the synthetic detergent industry. However, phosphate is discharged into rivers and lakes with the washing sewage, causing eutrophication of water quality, promoting the rapid propagation of algae, the lack of oxygen in the water, endangering the survival of aquatic animals, and thus becoming a major problem for environmental protection.

Liquid detergents containing sodium citrate have excellent washing performance, therefore, a variety of special detergents have been developed at home and abroad. Sodium citrate-containing liquid detergent also has other excellent properties, such as sodium citrate-containing special cleaning agent for certain metal appliances without corrosion, and thus can be used to clean valuable precision instruments;

Sodium citrate-containing special detergents cleaning appliances, the metal surface as bright as new, but also, after the cleaning of the waste liquid after treatment can be regenerated and reused to reduce the cost of washing. There are reports that in order to solve the problem of pesticide residues on vegetables and fruits and other food, the experts have developed a special detergent containing sodium citrate pesticide residues on vegetables and fruits.

Sodium citrate has good complexing properties, so it is widely used in the electroplating industry; in the construction industry, sodium citrate can be used as a retarder to join the concrete, in order to improve the tensile, compressive and anti-freezing properties of cement products; in environmental protection, sodium citrate can be used to remove sulfide in the industrial exhaust gas. In the ceramic industry, sodium citrate can be used as a grinding additive. In addition, sodium citrate in the brewing and photographic industry also has new uses, thus further broadening the application of sodium citrate.
