What is Liquid FeCl₂? Name and Properties
Liquid FeCl₂ is an aqueous solution of ferrous chloride (iron(II) chloride), typically prepared at commercial concentrations of 25–30% w/w. It is a crucial industrial chemical in wastewater treatment, electroplating, and textile dyeing—favored for its strong reactivity with Cr⁶⁺, its ability to initiate Fenton reactions, and its lower operating costs compared to other reducing agents.
Definition: FeCl₂ = Ferrous Chloride = Iron(II) Chloride = Iron(II) Alum
FeCl₂ (Iron(II) Chloride) is a salt of ferrous iron with hydrochloric acid. In Vietnamese commerce, this product is known by several synonyms:
- Liquid FeCl₂ — the most common abbreviation in the industry
- Ferrous Chloride Solution — International standard English name
- Iron(II) Chloride / Iron(II) Chloride — chemical nomenclature
- Ferrous sulfate 2 — a common colloquial name in the water treatment industry
- Iron(II) Chloride — IUPAC nomenclature

6 Main Applications of Liquid FeCl₂ in Industry
Liquid FeCl₂ (25–30%) is a potent, versatile reducing agent in industrial and municipal wastewater treatment. Fe²⁺ ions can reduce toxic Cr⁶⁺ to less toxic Cr³⁺, initiate the Fenton reaction to create hydroxyl radicals •OH, precipitate phosphorus, and neutralize H₂S—while also serving electroplating and textile dyeing applications.
1. Removal of Cr⁶⁺ from Electroplating Wastewater
Hexavalent chromium (Cr⁶⁺) is a highly toxic pollutant in electroplating wastewater. FeCl₂ is the most common and effective reducing agent for treating Cr⁶⁺ in acidic environments.
Practical effectiveness: Reduce Cr⁶⁺ from 50–200 mg/L to < 0,1 mg/L (QCVN 40:2011 column A) with a molar ratio of Fe²⁺:Cr⁶⁺ = 3,5–4:1 in practice.
2. Advanced Fenton Reaction (Advanced Oxidation)
The Fenton reaction uses the Fe²⁺/H₂O₂ pair to create hydroxyl radicals (•OH) — the strongest oxidizing agent after Fluorine, breaking down most difficult-to-decompose organic compounds:
Optimal conditions: pH = 2,5–3,5; Fe²⁺:H₂O₂ ratio = 1:5–1:10 (mol); temperature 20–40°C.

3. Treating H₂S and Odor in Drainage Systems
Hydrogen sulfide (H₂S) causes foul odors and corrodes concrete in sewers and pumping stations. FeCl₂ reacts directly with H₂S and sulfide ions:
Practical application: A dosing pump of FeCl₂ into the wastewater pumping station at a dose of 5–15 mg Fe²⁺/L is used to control H₂S < 1 ppm in the air.
4. Phosphorus-Removing Coagulation in Municipal Wastewater
Phosphorus (PO₄³⁻) causes eutrophication in ponds, lakes, and rivers. FeCl₂ precipitates phosphorus in the form of vivianite:
Effective: Reduce TP from 5–10 mg/L to < 0,5 mg/L (QCVN 14:2008 column A) with a Fe²⁺:P dose of 2–3 mol:mol. Suitable for urban wastewater treatment plants discharging into sensitive sources.
5. Electroplating & Metalworking Industry
In electroplating, FeCl₂ is used as:
- Reducing agent in the pre-treatment tank (pickling) — dissolves rust and surface oxides
- Electrolytic solution in electrochemical iron plating
- Reactive agent in the treatment of electroplating wastewater containing Cr⁶⁺, Ni²⁺, Zn²⁺
Concentration requirements: Electroplating commonly uses FeCl₂ 25% (small bath) or 30% (large bath & Cr⁶⁺ removal).
6. Textile Dyeing — Mordant & Color Wastewater Treatment
FeCl₂ plays two roles in the textile dyeing industry:
a) Mordant (colored substance): Fe²⁺ forms chelate complexes with natural and synthetic dyes, helping the color adhere firmly to the fabric fibers.
b) Treatment of colored wastewater: Fenton reaction (Fe²⁺ + H₂O₂) to decompose azo dyes and vat dyes — COD and color reduction > 80%.

Comparing FeCl₂ vs FeCl₃ — Choosing the Right One for Each Application
FeCl₂ (Iron II) and FeCl₃ (Iron III) are both common wastewater treatment chemicals, but they have different mechanisms and optimal applications. Choosing the wrong type leads to wasted chemicals, reduced treatment efficiency, and additional costs for pH adjustment. The comparison table below helps engineers and wastewater treatment contractors make the right decision.
| Criteria | FeCl₂ (Iron II) | FeCl₃ (Iron III) |
|---|---|---|
| Valence | Fe²⁺ | Fe³⁺ |
| Common form | Liquid 25–30% | Liquid 38–40% |
| Remove Cr⁶⁺ | ✅ Very effective — direct reducing agent | ❌ Not suitable — Fe³⁺ cannot reduce Cr⁶⁺ |
| Fenton reaction | ✅ Can thiet — only Fe²⁺ initiates Fenton | ❌ Not suitable — Fe³⁺ is a product, not a catalyst |
| SS flocculant/turbidity | ⚠️ Lower effectiveness | ✅ Better Fe(OH)₃ is a stronger coagulant. |
| Type of phosphorus | ✅ Effective | ✅ More efficient at low doses |
| H₂S removal | ✅ Very effective — creating stable FeS↓ | ⚠️ Less effective |
| Optimal pH | 2–5 (acids) | 4–8 (wider) |
| pH effect | Lower the pH by less | Lower the pH further — more alkali is needed to neutralize it. |
| Price | Lower | 15–25% higher |
choose FeCl₂ when: Cr⁶⁺ treatment, Fenton reaction, H₂S removal, electroplating systems
choose FeCl₃ When: flocculation of suspended solids, turbid water, water treatment

Same-day delivery (orders placed before 10 AM) with full VAT invoices and COA provided with each batch. Hotline: 0979.89.1929Do not purchase from unknown sources as FeCl₂ is a Class 8 hazardous chemical — ensure correct concentration and complete MSDS.
Which is more suitable for wastewater treatment: 25% or 30% FeCl₂?
30% FeCl₂ is more suitable when a smaller amount of diluent is needed (preferably for small systems or those requiring tight flow control). 25% FeCl₂ is easier to pump at low temperatures and has a lower risk of crystallization. In terms of treatment efficiency, both are equivalent when considering the same amount of Fe²⁺ actually loaded. Loc Thien engineers will provide free consultation to help you choose the most suitable option for your system.
What is the current price of liquid FeCl₂ per ton?
Liquid FeCl₂ prices fluctuate according to raw material prices and exchange rates. Loc Thien provides pricing based on quantity: tanker truck (≥ 20 tons) - best price, 1.000L IBC - average price, 200L drum - retail price.

Can Loc Thien deliver FeCl₂ by tanker truck to Quang Nam and Da Nang?
Yes. Loc Thien Chemicals has a warehouse in Da Nang, supplying liquid FeCl₂ by tanker and container to the entire region. Da Nang, Quang Nam (including Dien Nam - Dien Ngoc Industrial Park, Chu Lai, Tam Ky, Hoi An) and Quang Ngai (Dung Quat, Dung Quat Economic Zone). Delivery time: 2–3 days after order confirmation. Contact for price quote: 0979.89.1929.
How does liquid FeCl₂ differ from liquid FeCl₃ in wastewater treatment?
FeCl₂ contains Fe²⁺ (a reducing agent) — effective for Cr⁶⁺ removal , and Fenton reactionFeCl₃ contains Fe³⁺ (oxidizing/coagulating agent) — effective for Coagulation of suspended solids and treating turbid water. Using the wrong type is not only ineffective but also wastes unnecessary chemical costs. Loc Thien engineers provide free consultation to help you choose the right type based on your wastewater characteristics.
What is the dosage of FeCl₂ needed to remove Cr⁶⁺?
Theoretically, the molar ratio of Fe²⁺:Cr⁶⁺ is 3:1 (i.e., 3 moles of FeCl₂ reduce 1 mole of Cr⁶⁺). In practice, a dosage of 3,5–4:1 is used to ensure complete reaction. For example, with wastewater containing 50 mg/L Cr⁶⁺, approximately 540 mg/L Fe²⁺ (equivalent to approximately 2.150 mg/L of 25% FeCl₂) is needed. Optimal conditions: pH = 2–3; stirring for 15–30 minutes; then raising the pH to > 8 to precipitate Cr(OH)₃. See details: Fenton reaction FeCl₂ wastewater treatment.
What material is needed for a liquid FeCl₂ storage tank?
Liquid FeCl₂ storage tank obligatory use: HDPE, FRP or PVC. ABSOLUTELY NOT Use carbon steel, 304 stainless steel, or cast iron — FeCl₂ rapidly corrodes ferrous metals and some alloys. Valves, pumps, and exposed piping must also be made of PVC, PVDF, or HDPE. Peristaltic metering pumps or diaphragm pumps made of PVC/PVDF are the most suitable choice.
