Activated Alumina Al2O3 Description
Activated Alumina Al2O3 features good physical properties, high strength, non-toxic, tasteless, which has good ion exchange capability, above the entrance of 0.4 cm³ / g, making it high adsorption capacity. Because of its easy regeneration, long service life, the cost is relatively cheap, in fluoride removal methods, it is an economic, effective and practical method.
Activated alumina defluoridation agent is originally a kind of adsorption material, has a certain role of adsorption impurities, can be divided into macroporous (100-500a), mesopore (40-100a), microporous (40A). The pore diameter distribution varies from 10A to 500A. It has certain adsorption capacity for molecules smaller than its pore diameter.
Fluoride in water mainly exists in ionic state. In the process of fluoride removal, fluoride in ionic state is mainly removed from water. The adsorption of activated alumina accounts for a small part, and the most important thing is the ion exchange capacity of activated alumina.

Activated Alumina Al2O3 Applications
It can be widely used in deep drying of pyrolysis gas, ethylene and propylene, hydrogen production, air separation, instrument air drying and fluorine treatment of hydrogen peroxide, and also can be used to absorb H2S, SO2 and other pollutants, HF and water vapor in paraffin, especially in defluorination of drinking water.
