Overview

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.

Applications

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

Dosage and directions

Application Procedure

  1. Adjust pH of Cr⁶⁺-containing wastewater to ~2.5–3.5 using diluted sulfuric acid.

  2. Dose RXSOL Chromium 6 Neutralizer slowly with continuous mixing.

  3. Monitor Cr⁶⁺ reduction using dip test or UV spectrophotometry (540 nm with diphenylcarbazide method).

  4. Once reduction is complete, raise pH to 8.5–9.0 using lime or sodium hydroxide to precipitate Cr³⁺.

  5. 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)

Characteristics and notes

Small Spill

Use appropriate tools to put the spilled solid in a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and dispose of according to local and regional authority requirements.

Large Spill

Use a shovel to put the material into a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and allow to evacuate through the sanitary system. Be careful that the product is not present at a concentration level above TLV. Check TLV on the MSDS and with local authorities.

Precautions

Keep locked up.. Do not ingest. Do not breathe dust. Avoid contact with skin. Wear suitable protective clothing. In case of insufficient ventilation, wear suitable respiratory equipment.
