Oxalic Acid Dihydrate (Industrial Grade): Innovative & Eco-friendly Applications
Core Component of New Eco-friendly Rust Removers
In green industrial cleaning, oxalic acid dihydrate replaces traditional strong acid rust removers. It removes metal surface oxidation layers through gentle chelation, reducing substrate corrosion damage while meeting environmental production standards.
Key Material in Lithium Battery Recycling & Purification
In new energy battery recycling, oxalic acid dihydrate effectively dissolves and separates metal elements from cathode materials, enabling efficient recovery of valuable metals like cobalt, nickel, and lithium to enhance resource recycling rates.
Heavy Metal Precipitation Agent for Wastewater Treatment
In industrial wastewater treatment, oxalic acid dihydrate forms stable complexes with heavy metal ions. Through precipitation separation processes, it effectively removes harmful metals like copper, lead, and chromium from wastewater to meet environmental discharge standards.
