Weight: 11 lb (5kg)
Sale price$83.00


Activated bleaching earth, also known as activated clay made from bentonite. It is a highly active adsorbent and the most widely used in decolorization in the oil industry.

Activated bleaching earth has a strong adsorption capacity for pigments in oil, especially chlorophyll and other colloidal impurities. It has a stronger adsorption capacity for basic atomic groups and polar atomic groups.

MarkNature activated bleaching earth has a strong adsorption capacity, lower oil carrying rate, high activity, easy precipitation, and filtration.

Activated bleaching earth is widely used in the decolorization and purification of petrochemical, pharmaceutical, oleochemical, animal, and vegetable oils, it can effectively remove pigments, mycotoxins, and odors in edible vegetable oils.

As a decolorizing agent, it is also widely used in soap, plastic, resin, food, paint, decontamination powder, brewing and other industrial production.

As an adsorbent, it is also widely used in the removal process of organic phosphorus, organic sulfur, aflatoxin, and other harmful substances.

It can also polymerize olefins into high-grade lubricating oil, and also has a good effect on radioactive sewage treatment.
