Characteristics and Application Precautions of EDTA Dipotassium Acidity and Alkalinity

 

EDTA dipotassium is an important chelating agent. In medicine, it can be used as a Anticoagulant to help blood testing complete more smoothly and effectively. The key to its performance determines the quality of its use results, such as the purity, pH value, molecular weight, solubility, and other important indicators of EDTA potassium. Below, we will focus on introducing the acidity and alkalinity of EDTA potassium.

 

1、 EDTA dipotassium acidity and alkalinity

EDTA dipotassium is a salt, which can be dissociated into divalent potassium ions and EDTA root ions in water. Its pH value is 4.8 ± 1 (5% aqueous solution, g/ml), which is acidic. According to its acidity and alkalinity, it can be used in different fields except as a Anticoagulant for blood collection.

 

2、 EDTA potassium application

1. Chelating agent: EDTA dipotassium acid, as a strong chelating agent, can form stable complexes with various metal ions, making it widely used in fields such as coordination chemistry of metal ions, metal analysis, and wastewater treatment.

2. Chelating titration: EDTA dipotassium is commonly used in complex titration. By adding EDTA potassium solution dropwise to a solution containing metal ions, the content of metal ions can be determined, thereby achieving quantitative analysis.

3. Metal ion control: Due to the certain effect of EDTA potassium on metal ions, it can be used in industry to control metal ions, such as as as a metal corrosion inhibitor and a stabilizer for metal ions.

 

3、 EDTA Potassium Dioxide Precautions

1. PH regulation: The chelating properties of EDTA dipotassium are affected by pH value, and in some experiments and applications, it is necessary to adjust the pH value of EDTA dipotassium solution to achieve better chelating effects.

2. Storage in dark: Both EDTA potassium powder and prepared solution should be kept away from direct sunlight, as light can degrade their stability and activity.

3. The blood experimental specimen must ensure sufficient anticoagulation, so it should be inverted and mixed 5-8 times as soon as possible after blood collection to prevent the occurrence of small clots, especially when the blood collection temperature is too high. If anticoagulation is not complete, it can easily lead to local coagulation.

 

The acidity and alkalinity of EDTA potassium can ensure its stability in experiments, but it does not exist in isolation and needs to be combined with other key indicators to ensure superior product quality. As a raw material manufacturer of blood vessel additives, Desheng has always been strict in the key indicators of its products, and is equipped with professional personnel to supervise and rectify.
