Chromium 6 Neutralizer (or Hexavalent Chromium Neutralizer) is a chemical treatment agent used to reduce Chromium VI - a highly toxic, carcinogenic form of chromium - into Chromium III, which is significantly less harmful and more environmentally stable.
RXSOL Chromium 6 Neutralizer is a high-performance liquid formulation designed to safely and efficiently reduce hexavalent chromium (Cr⁶⁺) to trivalent chromium (Cr³⁺) in industrial wastewater streams. The reduced Cr³⁺ can be precipitated and removed as Cr(OH)₃, ensuring compliance with environmental discharge norms.
What is Chromium VI Neutralizer?
-
Found in industrial effluents such as from metal plating, leather tanning, pigments, and chromate production.
-
Highly toxic, especially to humans and aquatic life.
-
Recognized carcinogen (linked to lung cancer, nasal irritation, ulcers).
Application Areas
-
Wastewater treatment plants
-
Metal finishing units
-
Leather tanneries
-
Chemical manufacturing facilities
Application Procedure
-
Adjust pH of Cr⁶⁺-containing wastewater to ~2.5–3.5 using diluted sulfuric acid.
-
Dose RXSOL Chromium 6 Neutralizer slowly with continuous mixing.
-
Monitor Cr⁶⁺ reduction using dip test or UV spectrophotometry (540 nm with diphenylcarbazide method).
-
Once reduction is complete, raise pH to 8.5–9.0 using lime or sodium hydroxide to precipitate Cr³⁺.
-
Filter or settle to remove Cr(OH)₃ sludge.
Typical Dosage:
~6.0–8.5 parts of RXSOL-68-6803-050 solution per part of Cr⁶⁺ (adjust based on actual Cr⁶⁺ ppm)
Why is it Important?
-
Helps industries comply with environmental discharge norms
-
Prevents soil and groundwater contamination
-
Protects human health and biodiversity
Safety & Handling
-
Avoid contact with skin, eyes, and clothing.
-
Use in well-ventilated areas.
-
Do not mix with acids in confined spaces — may release SO₂ gas.
-
Refer to MSDS before use.
