Differences between Nitrilotriacetic Acid and Nitrilotriacetic Acid Trisodium:
Form Availability: Nitrilotriacetic Acid (free acid) is only available as solid powder or crystals. Trisodium Nitrilotriacetate is available in both solid and liquid forms for flexible use.
Dissolving in Water: The acid form is poorly soluble in water and needs alkaline conditions to dissolve. The trisodium salt dissolves easily in water, making it ready-to-use for many applications.
pH Value: Nitrilotriacetic Acid has low pH (acidic) around 2-3 in solution. Trisodium Nitrilotriacetate has high pH (alkaline) typically 10-12, suitable for different formulation needs.
Common Applications: The acid form is often used in lab synthesis and special reactions. The trisodium salt is preferred for industrial water treatment, detergents, and chelation applications where quick dissolving matters.
Packaging Options: We supply Nitrilotriacetic Acid as solid in bags or drums. Trisodium Nitrilotriacetate is available as solid powder or concentrated liquid solution in various container sizes.
Types of Nitrilotriacetic Acid
| Feature | Solid NTA | Liquid NTA |
| Solubility | Slightly soluble in hot water | Better solubility, ready-to-use |
| Storage | Store in cool, dry place. Stable at room temperature for weeks | Store at -20°C (use within 1 month) or -80°C (use within 6 months) |
| Best For | • Metal ion analysis • Rare metal extraction • Industrial applications | • Biomedical research • Drug development • Lab experiments needing quick use |
| Cost | Higher cost per unit | Lower cost, faster absorption |
| Choose If | You need long-term storage or industrial-scale use | You need ready-to-use solution for research |
Key Advantages of Nitrilotriacetic Acid (NTA)
Strong Chelating Power: NTA forms stable complexes with metal ions like calcium, magnesium, iron, copper, and zinc, making it highly effective for metal ion control.
Versatile Applications: It is widely used in water treatment, detergents, electroplating, polyurethane foam production, and as a stabilizer in styrene production.
Eco-Friendly Alternative: NTA is readily biodegradable and serves as a replacement for phosphates in detergents, helping to prevent water eutrophication.
Laboratory Essential: Used in protein purification (His-tag method), complexometric titrations, and as a buffering agent in biochemical assays.
High Purity Available: We supply NTA with purity ≥99%, meeting strict quality standards for industrial and research applications.
Free Samples Available: Contact us to request a free sample and test the quality of our NTA in your own process before ordering.
What is Nitrilotriacetic Acid Used for
- Wastewater Treatment: Removes heavy metals from industrial discharge to protect the environment.
- Cleaning & Detergents: Powerful chelating agent for metal ion control and industrial surface descaling.
- Medicine: Used to treat heavy metal poisoning by facilitating the elimination of toxic ions.
- Agriculture: Enhances nutrient availability in fertilizers through metal chelation.
- Analytical Chemistry: Functions as a complexing agent for metal ion detection and analysis.
- Waste Remediation: Applied in the sequestration and immobilization of radionuclides in radioactive waste.
FAQ of Nitrilotriacetic Acid
NTA can biodegrade in wastewater treatment plants and natural waters under many conditions. Studies show no harmful effects at expected environmental levels
Yes. Every shipment includes Certificate of Analysis (CoA) confirming purity, appearance, and specifications, plus SDS and other export documents.
NTA decomposes at 242-246°C. It has poor solubility in water (0.128 g/100 mL at 22.5°C) but dissolves well in alkaline solutions.
NTA offers several advantages over EDTA:
Better for environment: NTA is readily biodegradable, while EDTA persists much longer in nature .
More efficient: NTA is a smaller molecule, so 32% less product is needed to bind the same amount of metals .
Cost-effective: Higher efficiency means lower treatment costs for many applications .
Faster degradation: NTA breaks down in 1-2 days in water systems. EDTA takes much longer .
Choose NTA when you need a sustainable, cost-efficient chelating agent.
Nitrilotriacetic Acid Packaging
Powder: 25kg multi-layer paper bags (lined with plastic bags) or high-specification plastic woven bags are used.
Liquid: 25kg plastic drums, 250kg polyethylene drums, or 1000L IBC containers
Store in a cool, dry, well-ventilated area in tightly sealed original containers, keeping strictly away from strong oxidizers, bases, and metals
