Overview
Dipotassium oxalate (CAS 583-52-8 ), also known as potassium oxalate, is the dipotassium salt of oxalic acid used industrially as a chelating and sequestering agent. It binds and immobilizes metal ions in solution.
This chemical enables effective cleaning, precipitation, and process control across mineral processing, textile, and water treatment operations. In mining and metal processing, it precipitates calcium and heavy metal ions from process streams.
This functionality supports ore separation and effluent control. Textile manufacturers apply it as a reducing and cleaning agent during fabric preparation, helping to remove metal impurities that would otherwise interfere with dyeing uniformity.
In leather processing and paper manufacturing, it functions as a sequestrant to control calcium hardness in process water. This protects equipment and improves product consistency across various manufacturing stages.
Water treatment operations use it to complex interfering metal ions before downstream chemical dosing steps. This ensures that the treatment process remains efficient and free from unwanted mineral interference.
Dipotassium oxalate is supplied as a white crystalline powder or granule. It is available in technical grade for industrial applications, with monohydrate form being the standard commercial specification for most buyers.
Packaging typically ranges from 25 kg bags to bulk quantities depending on application volume. Our supply chain ensures consistent quality and reliable delivery for large-scale industrial requirements.
