Product Overview

W&Q's Ferrous Sulfate Monohydrate (molecular formula: FeSO₄·H₂O) is a high-purity inorganic iron compound, presenting as off-white to light green crystalline powder with good water solubility and chemical stability. Iron, as an essential trace element, is a core component of hemoglobin, myoglobin, and various enzymes, playing an irreplaceable role in oxygen transport, energy metabolism, and immune regulation for humans, animals, and plants. W&Q manufactures ferrous sulfate monohydrate in line with strict GMP and ISO standards, utilizing advanced refining processes and high-quality raw materials to ensure consistent purity, low heavy metal content, and reliable bioavailability. Our product is widely applied in animal nutrition, agricultural fertilizers, food supplements, water treatment, and pharmaceutical fields, providing a premium iron source for global customers.

Product Benefits

1. Hemoglobin Synthesis Support: Iron is the key component of hemoglobin, which is responsible for oxygen transport in the blood. W&Q’s ferrous sulfate monohydrate provides bioavailable ferrous iron (Fe⊃2;⁺), which is easily absorbed by the body, effectively preventing and improving iron deficiency anemia in humans and animals.

2. Animal Growth & Reproduction Enhancement: For livestock and poultry, adequate iron supplementation promotes growth performance, enhances immune function, and improves reproductive efficiency. It helps avoid iron deficiency-related issues such as poor growth, low immunity, and reduced fertility in young animals, increasing feed conversion rates and breeding benefits.

3. Plant Nutrition & Yield Improvement: As a critical micronutrient for plants, iron promotes chlorophyll synthesis and photosynthesis, preventing chlorosis (yellowing of leaves). It enhances crop resistance to stress and diseases, improving yield and nutritional quality. W&Q’s product is easily absorbed by plants, suitable for soil application, foliar fertilization, and compound fertilizer blending.

4. Versatile Industrial Applications: In water treatment, it is used for flocculation and decolorization, effectively removing impurities and heavy metals. In pharmaceuticals, it serves as a raw material for iron supplements. It also acts as a reducing agent and pigment intermediate in chemical industries, with stable performance and cost-effectiveness.

Usage

- Animal Nutrition: Added to livestock and poultry feed. Recommended dosage varies by species and growth stage: 80-150 mg/kg for poultry feed, 100-200 mg/kg for swine feed, and 50-100 mg/kg for ruminant feed. W&Q offers customized dosage guidance based on specific breeding scenarios.

- Agricultural Fertilizers: Used for iron-deficient crops like fruits, vegetables, and grains. For soil application, the dosage is 20-40 kg/ha; for foliar spray, dilute to a 0.2-0.5% solution and apply 2-3 times during the growing season, with an interval of 7-10 days.

- Food & Pharmaceutical Supplements: Used in multivitamin formulations and iron supplements. The daily recommended intake for adult humans is 8-18 mg of elemental iron (equivalent to appropriate ferrous sulfate monohydrate content), with adjustments for pregnant women, children, and anemic individuals.

- Water Treatment: The dosage is 50-200 mg/L depending on water quality, used for flocculation in drinking water and wastewater treatment to remove turbidity and heavy metals.

Storage: Store in a dry, cool, and well-ventilated warehouse, away from moisture, direct sunlight, and oxidizing substances. Keep sealed tightly to prevent oxidation (turning yellow/brown) and caking. Shelf life is 24 months under proper storage conditions.

FAQ

Q1: Is ferrous sulfate monohydrate safe for humans and animals?

A1: Iron is essential but toxic in excess. The daily maximum safe intake for humans is 45 mg of elemental iron. Acute poisoning (nausea, diarrhea, abdominal pain) may occur with high-dose ingestion. W&Q’s products are formulated within safe limits, and strict adherence to recommended dosages is crucial.

Q2: Why does ferrous sulfate monohydrate turn yellow? Does it affect efficacy?

A2: Yellowing is caused by oxidation of ferrous iron (Fe⊃2;⁺) to ferric iron (Fe⊃3;⁺) when exposed to moisture and air. Oxidized products have reduced bioavailability. W&Q adopts anti-oxidation packaging and production processes to minimize oxidation, and proper sealed storage is recommended.

Q3: What is the difference between ferrous sulfate monohydrate and heptahydrate?

A3: Monohydrate has higher iron content (≈30%) and better stability, less prone to moisture absorption and oxidation, suitable for long-term storage and wide applications. Heptahydrate (green vitriol) has lower iron content (≈20%) and strong hygroscopicity, prone to caking. W&Q’s monohydrate product is more cost-effective for large-scale industrial and agricultural use.

Q4: Does it comply with international quality standards?

A4: Yes. W&Q’s ferrous sulfate monohydrate meets global standards such as USP, BP, FCC, and GB/T 10531-2016, with heavy metal content (Pb, Cd, As) below 10 ppm, fully satisfying food, feed, pharmaceutical, and industrial grade requirements.
