Activated Alumina Defluoridation
1.Activated alumina defluoridation is a kind of adsorption material
2.Its basic characteristics are high specific surface area and high pore volume
3.It has the function of absorbing impurities
Product Introduction
Activated alumina defluoridation
It is made of high-purity alumina through scientific preparation and catalytic finishing. Its adsorption can be used as a desiccant and can also remove fluorine harmful to human body in water.
It is similar to anion exchange resins, but the selectivity of fluoride ions is greater than that of anion resins. It has good adsorption and defluorination effect, stable capacity, and activated alumina absorbs 6400 grams of fluorine per cubic meter.
Characteristics:
① Good physical properties,
② High strength,
③ Non-toxic,
④ Tasteless,
Activated alumina defluoridation has good ion exchange capability
Above the entrance of 0.4 cm³ / g make it has 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.

Adsorption Mechanism:
Activated alumina defluoridation is originally a kind of adsorption material.
It has a certain role of adsorption impurities.
It 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 defluoridation.
