Descripción del producto

Ethylenediaminetetraacetic acid (EDTA) is an amino polyacid. Because it can form superfluous compounds with most metal ions, it becomes a general-purpose strong superfluous agent. Although the redundant effects of EDTA have been used for extraction, cation exchange, separation of rare elements, volumetric analysis of calcium, magnesium, and barium, hard water softening, and use as a masking agent, metal cleaning agent, antidote for heavy metal poisoning, and bactericide, etc. There are many applications, but the in-depth research on its structure and overlapping mechanism is still after ***8.



Studies have explored the causes of platelet (PLT) aggregation caused by EDTA-K3 and the corresponding measures. Three patients with typical EDTA-dependent platelet pseudodecrease (PTCP) were used XE****0 hematology analyzer to observe the changes of platelets in different time periods with different anticoagulants (EDTA-K3, sodium citrate and lithium UFH). The results showed that 3 typical EDTA-PTCP patients were displayed beside the instrument, and all three kinds of anticoagulants of platelet could be tested immediately, and the results were similar. After more than *0 minutes, EDTA-K3 anticoagulation decreased significantly, while sodium citrate and UFH Lithium anticoagulation also has varying degrees of influence on platelets.



Application of EDTA tripotassium:

1. As an anticoagulant for blood cell analysis. The use of ethylenediaminetetraacetic acid (EDTA) salt as an anticoagulant for blood cell analysis was determined by the International Committee for Blood Standards (ICSH) in ***3 and is widely used. The use of EDTA-K3 anticoagulant blood for blood analysis in my country is not long, and there are few reports on the false reduction of EDTA-dependent platelets. There is a view that this phenomenon is an autoimmune disease, because in this group of people A large proportion of their serum immunoglobulins are elevated, and antiplatelet autoantibodies and anticardiolipin antibodies are positive. Incubation of plasma from such patients with platelets of healthy persons can cause platelet aggregation in healthy persons, while plasma from healthy persons cannot cause platelet aggregation in such patients.



In patients with EDTA-dependent platelet pseudo-decrease, when using EDTA-K3 anticoagulant blood to count with a blood analyzer, a large number of PLT aggregates together, resulting in a pseudo-reduction of PLT count. At the same time, the volume of some PLT aggregates is equivalent to the volume of WBC, and It cannot be destroyed by hemolysin, which also makes the WBC count falsely increase, which will cause various inaccurate prompts for the classification of WBC by the instrument. The PLT histogram shows the presence of large platelets or platelet aggregation, and the WBC histogram will also undergo certain changes. . Studies have shown that unexplained low platelet counts are found when EDTA-K3 anticoagulant blood is used for blood analysis. The patient should be manually inspected for blood slices and PLT manual count review, or diluted with non-anticoagulated peripheral blood Directly use the instrument for blood cell analysis to review the PLT count to correctly understand the true level of the patient's PLT. Especially patients with tumors, autoimmune diseases, pulmonary heart disease, pregnant women, advanced liver disease, etc.



2. Prepare a self-cleaning borosilicate glass rod. EDTA tripotassium is mixed with deionized water, ****4 parts of aluminum isopropoxide, etc., and then heated to ****5℃ to form a colloidal liquid, and then reacted with tetrabutyl titanate, ****5% ammonia, ethanol After the colloidal liquid is mixed and stirred evenly, a self-cleaning paint is made. After the surface of the borosilicate glass rod is cleaned, it is placed in the self-cleaning paint and soaked for ****4 minutes, then taken out and placed in a high-temperature furnace After the sintering process, the finished product of the high borosilicate glass rod with self-cleaning function can be obtained. In the preparation process, tripotassium ethylenediaminetetraacetic acid is used as an important additive in the colloidal liquid, which can effectively improve the adhesion performance of the prepared colloidal liquid, improve the uniformity of the AlOOH colloidal dispersion, and prevent its precipitation. This phenomenon has become an important colloidal dispersant.



3. Preparation of a thermal insulation coating for exterior walls of buildings. It includes *0～**0 parts of pure acrylic emulsion, *0～*0 parts of Ta2O*-ZnO-SnO2 composite oxide powder, 5～*0 parts of potassium edetate, 2～5 parts of kaolin, and 1～5 parts of borax. , 2～5 parts of antifreeze, 5～*0 parts of film forming aids, 1.5～2.3 parts of pyrophosphate, 1～2 parts of thickener, 2～3 parts of polyoxyethylene polyoxypropylene pentaerythritol ether and o-nitrobenzene 0.5 to 1 part of sulfonic acid and **0 to **0 parts of water. It is found through experiments that the introduction of tripotassium ethylenediaminetetraacetate in exterior wall paint can significantly improve the acid corrosion resistance of the paint, so that in cities with severe acid rain, the paint of the present invention can also ensure a good service life and is not easy to corrode and fall off. .



I believe that after reading the above description of the application of tripotassium EDTA, I know that it has a wide range of applications.
