Product description
Product overview
Diethylenetriaminepentaacetic acid ammonium iron salt solution (DTPA-FeNH₄) is a high-efficiency organic chelated iron solution. The product is a reddish-brown viscous liquid with iron content ≥6%, CAS 85959-68-8, molecular formula C₁₄H₁₈N₃O₁₀Fe(NH₄)₂, molecular weight 480.2. Neutral pH (7.0-8.0) is safer for crops, widely used in medicine, water treatment, textile auxiliaries, agriculture, and other industries.
Key Advantages
- High iron contentIron content ≥6%, effective iron supplementation
- Neutral pHpH 7.0–8.0: safer for crops and equipment
- Moderate DensityDensity 1.25-1.35 g/mL, convenient for dosing and mixing.
- Ease of useLiquid form: no dissolution required, applied after direct dilution
- Applications across various industriesPharmaceuticals, water treatment, dyeing and printing, detergents, leather, paper industry, agriculture, and other fields.
Application recommendations
Recommended method of application
Water Treatment
- Recommended dosage: 5-50 mg/L (depending on water quality).
- Directions for Use: add directly to the recirculating water system
- Effect: effectively chelates calcium and magnesium ions, prevents scale formation.
Printing and dyeing auxiliaries
- Recommended dosage: 0.5-2 g/L
- Directions for Use: use together with dye, adjusting pH to neutral.
- Effect: chelates metal ions in water, improves color uniformity and color fastness.
Agricultural Fertilizer Application
- Recommended dosage: 1-3 L/ha, dilute 500-1000 times.
- Directions for Use: drip irrigation, fertigation, or foliar spray.
- Effect: iron supplementation, prevention and correction of plant chlorosis
Precautions:Store in a dry place, avoid contact with alkaline substances. After opening, use as soon as possible, keep sealed to prevent deterioration. The specific application method and dosage can be adjusted according to actual process conditions.
