Etidronic Acid/HEDP Description
What is Etidronic Acid/HEDP?
HEDP is an efficient organic phosphonic acid compound, and industrial products are colorless to light yellow transparent liquids. HEDP is easily soluble in water, and soluble in methanol and ethanol. Hydroxyethylphosphonic acid is a chemical raw material commonly used in industrial water treatment, household cleaning products, and personal care products.
HEDP is widely used in industrial circulating cooling water systems such as power, chemical, metallurgical, and fertilizer industries, as well as for scale and corrosion inhibition in medium and low pressure boilers, oilfield water injection, and oil pipelines; In the textile industry, it can be used as a cleaning agent for metals and non metals, a peroxide stabilizer and fixing agent for the dyeing industry, a complexing agent for cyanide free electroplating industry, and a carrier for radioactive elements in the pharmaceutical industry.

Etidronic Acid/HEDP Applications
Industrial water treatment (core application):
HEDP mainly plays a role in scale and corrosion inhibition in this field.
As a scale and corrosion inhibitor: HEDP can form stable complexes with metal ions such as calcium and magnesium, prevent the formation of scale such as calcium carbonate and calcium sulfate, and form a protective film on the metal surface to slow down corrosion.
Application System: Widely used in circulating cooling water systems, medium and low pressure boilers, oilfield water injection, and oil pipelines in industries such as power, chemical, metallurgical, and fertilizer.
Usage concentration: When used as a scale inhibitor, the commonly used concentration is 1-10 mg/L, and when used as a corrosion inhibitor, it is 10-50 mg/L.
Other industrial sectors:
Electroplating industry: As a universal complexing agent for cyanide free electroplating, it is used to improve the performance of electroplating solutions and enhance the quality of coatings.
Textile printing and dyeing industry: used as a stabilizer and fixing agent for peroxides (such as hydrogen peroxide).
Cleaning agent: used in industries such as textiles and electronics for cleaning metals and non metals. When used as a cleaning agent, the concentration is usually 1000-2000 mg/L.
Special and daily use areas:
Medical field: High purity HEDP can be used as a carrier of radioactive elements, such as in tumor examination processes.
Daily chemicals: can be used as additives in products such as phosphate free detergents.
