Mga Katangian at Paggamit:
Diethylenetriamine pentaacetic acid (CAS 67-43-6), abbreviated as DTPA, is a highly efficient organic chelating agent that can form stable complexes with a variety of metal ions.
1. Pang-industriya na gamit
Water treatment: DTPA is used in circulating cooling water and boiler water systems to effectively chelate metal ions such as calcium and magnesium, prevent scale formation, and improve equipment operation efficiency.
Metal cleaning: In the process of cleaning and rust removal, metal ions are removed by chelation to enhance the cleaning effect.
Papermaking industry: In the bleaching process, DTPA can remove metal ions such as iron and copper, reduce bleaching interference, and improve the whiteness and quality of pulp.
Electroplating industry: Regulate the concentration of metal ions in the electroplating solution to ensure the uniformity of the coating and improve the surface quality.
2. Gamit sa agrikultura
Trace element fertilizer: As a chelating agent for trace elements such as iron, zinc, and manganese, DTPA significantly improves the absorption efficiency of plants for metal elements, promotes healthy growth of crops and increases yields.
Plant nutrients: Maintain the stability of trace elements in the solution and optimize the use of nutrients by crops.
3. Medical and radioactive applications
Radioactive chelation therapy: DTPA and its sodium salt are used to chelate radioactive metals (such as uranium and plutonium) to accelerate the discharge of radioactive substances in the body, and are suitable for radioactive contamination treatment.
Medical imaging: DTPA combines with gadolinium to form gadolinium-DTPA, and the contrast agent is used in nuclear magnetic resonance (MRI) imaging to improve image clarity and diagnostic accuracy.
4. Proteksiyon ng kapaligiran
Heavy metal remediation: By chelating heavy metal ions, DTPA facilitates the extraction and treatment of heavy metals in soil remediation.
Wastewater treatment: Used to remove heavy metal ions in wastewater and reduce pollutant concentrations.
5. Iba pang mga application
Laboratory reagents: Used for separation and quantitative analysis of metal ions in chemical and biochemical experiments.
Food and textile industry: DTPA can be used as a color stabilizer in food processing and an auxiliary agent in the textile industry to optimize process effects.
