Ethylenediaminetetraacetic Acid Dipotassium Salt Dihydrate, also known as EDTA-2K, is a common complexing agent. Because it complexes with calcium in blood to inactivate calcium and can prevent blood from clotting, it is commonly used to prepare anticoagulants, anticoagulation tubes, and it is used in matching whole blood analyzers, which is widely used.

The International Blood Standards Committee recommends that using the EDTA-2K anticoagulation to complete blood count. The use of EDTA-2K as an anticoagulant in vacuum blood collection tubes can preserve the leukocyte hyperplasia in a short time, prevent platelet aggregation, and save platelets.

In addition to being an anticoagulant, EDTA-2K has many applications in industrial production, environmental optimization and other fields.

EDTA-2K is used as a retardant to replace borax used in the traditional magnesium phosphate cement. It has better retarding effect, can prolong the setting time of magnesium phosphate repair system, ensure the strength of magnesium phosphate cement, and make the quick repairing material more widely used in rapid repair areas such as highways, bridge decks, and airstrips.

During the production of oil fields,EDTA-2K is also used as a stabilizer to form a desulfurization synergist, which can not only maintaining the stability of the desulfurization synergist, but also chelate metal ions such as Ca 2+ and Mg 2+ in the operating system to be treated to stabilize the whole Water quality of the operating system. The desulfurization synergist can achieve the purpose of removing sulfide through effective chemical reaction with sulfide in the equipment, and has a good desulfurization effect, Ensure the safety of oilfield construction.

EDTA-2K is also commonly used in the preparation of deodorants, such as toilet deodorants, pesticides and odor molecule removal agents, etc. In addition, according to the description of related patents, EDTA-2K is sequentially subjected to high-temperature calcination, pickling, water washing and drying processes to prepare activated carbon.
