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.
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).

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)
Helps industries comply with environmental discharge norms
Prevents soil and groundwater contamination
Protects human health and biodiversity
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.
Acidic water causing problems for system. Acid neutralizer help to raise the pH levels.
