Potassium Permanganate (Technical Grade)

Potassium Permanganate for Water Treatment and Oxidation

Potassium Permanganate is a dark purple crystalline solid and a strong oxidising agent. Potassium permanganate dissolves in water to give an intense purple solution. It oxidises iron, manganese, odours and organic matter, which makes it valuable in water treatment.

We stock technical grade Potassium Permanganate made by Star Oxochem Pvt. Ltd. in Gujarat, India. The drums carry the NSF certification mark and hold 50 kg net. Wisdo Merchants Chemical Division delivers it across Kenya and East Africa from Industrial Area, Nairobi.

Features and Benefits of Potassium Permanganate

• Strong oxidiser: Converts dissolved iron and manganese into solids that can be filtered out.

Applications of Potassium Permanganate

Water Treatment

Treatment plants and borehole operators use it to remove iron, manganese and hydrogen sulphide, and to control taste, odour and algae. It also regenerates manganese greensand filters. Coagulation with our alum coagulant often follows. See our water treatment chemicals.

Laboratories and Chemical Processing

Laboratories use it in titrations and oxidation reactions. Chemical plants use it as an oxidant in manufacturing. Browse our laboratory reagents.

Other Uses

It is also used in aquaculture, metal surface treatment and some disinfection applications. Follow local regulations and dosing guidance.

Safety and Handling

• Oxidiser: It may intensify fire. Keep it away from fuels, oils, organic matter and reducing agents.
• Harmful if swallowed.
• Corrosive to eyes and skin: Wear goggles, gloves and protective clothing. It stains skin and fabric brown.
• Environment: Very toxic to aquatic life. Prevent spills from reaching drains.
• Do not mix with acids, glycerine, alcohols or other organic chemicals.

Always read the Safety Data Sheet before use.

Storage and Shelf Life

Store drums tightly closed in a cool, dry place, separate from combustible materials, acids and reducing agents. Keep drums upright and protected from damage.

Frequently Asked Questions

Why is potassium permanganate purple?
The permanganate ion absorbs green light, so its solutions look deep purple.

Can it remove iron from borehole water?
Yes. It oxidises dissolved iron so that it can be filtered out. A water test helps set the right dose.

Do you deliver outside Nairobi?
Yes. We deliver across East Africa and confirm freight and timelines with your quotation.
