On the Application of Calcium Sodium Ethylenediamine Tetraacetic Acid
Calcium Sodium Ethylenediamine Tetraacetic Acid, that is, EDTA CaNa -2, has significant applications in many fields.

In the field of medicine, it is often used as an antidote. If the human body accidentally ingests heavy metals such as lead, mercury, and copper, EDTA CaNa -2 can tightly combine with heavy metal ions by virtue of its unique chemical structure to form a stable and soluble complex, which is excreted from the body by the kidneys to help the human body detoxify the toxicity of heavy metals. In case of lead poisoning, timely use of EDTA CaNa -2-containing agents can effectively reduce the lead content in the body and relieve the symptoms of poisoning.

In the food industry, EDTA CaNa -2 plays an important role in color protection and anti-corrosion. Added to canned foods, it can chelate metal ions, prevent oxidation, discoloration and deterioration of food caused by metal ions catalysis, prolong the shelf life of food, and maintain the color and flavor of food. For example, in some canned fruits, after adding EDTA CaNa 2O, it can maintain a bright color and original taste for a long time.

In the industrial field, EDTA CaNa 2O is of great significance for water quality treatment. Hard water contains a lot of calcium and magnesium plasma, which can cause problems such as pipe scaling and equipment corrosion. When EDTA CaNa 2O is put into water, it can be complexed with calcium and magnesium ions to soften hard water, ensure the smooth operation of industrial equipment, and reduce energy consumption and equipment maintenance costs. In the printing and dyeing industry, it can also be used as a dyeing aid to improve dyeing uniformity and fastness.

EDTA CaNa 2O plays a key role in many fields such as medicine, food, and industry due to its unique chemical properties, and has made significant contributions to the development of various industries and the improvement of people's quality of life.
