Core Industrial Applications
Water Treatment Systems
Prevents scale formation in boilers and cooling towers by chelating Ca²⁺/Mg²⁺ ions. Typical dosage: 50-200 ppm depending on water hardness.
Food Preservation
Maintains color stability in canned vegetables (usage level: 80-120 mg/kg) and prevents oxidation in oils.
Pharmaceuticals
Used in anticoagulant preparations (0.05-0.1% w/v) and as stabilizer in antibiotic formulations.
Operational Protocols
Solution Preparation
For laboratory use: Dissolve 186.1g EDTA-ACID in 800mL DI water, adjust pH with NaOH, then bring to 1L total volume.
Safety Handling
PPE Requirements: Nitrile gloves, goggles, and N95 mask when handling powder form.
Client Implementations
Case 1: Municipal Water Plant (Zhejiang, China)
Challenge: 45% scaling reduction in heat exchangers within 6 months of EDTA-ACID implementation.
Case 2: Cosmetic Manufacturer (Guangzhou)
Solution: 0.08% EDTA-ACID in skincare serums improved product stability from 6 to 18 months.
