what is Activated alumina ？

Activated alumina is a porous , high dispersion of solid materials, a large surface area, the porous surface with the required catalytic properties , such as adsorption , surface activity, good thermal stability, it is widely being used as chemical catalysts and catalyst supports.

Appearance

activated alumina is white spherical porous particle, particle size uniform, smooth surface, mechanical strength, moisture absorption is strong, not expanding crack remains intact after water absorption, non-toxic, odorless, insoluble in water, ethanol, has very strong adsorption to fluorine, mainly used for high fluoride areas fluoride in drinking water.

Role

Activated alumina on the gas, water vapor, and some of the liquid water has selective adsorption ability. After the adsorption saturation can be in about 175-315 ℃ heating to remove water and resurrection. Adsorption and resurrection for many times. In addition to the used as a desiccant, but also from the pollution of the oxygen, hydrogen, carbon dioxide adsorption oil steam, gas, etc. And can be used as a catalyst and catalyst carrier and carrier of chromatographic analysis.

Activated alumina chemical alumina category, mainly for the adsorbent, water purifier, catalyst and catalyst carrier, according to different purposes, the raw materials and different preparation methods

The main factors influencing the activated alumina adsorption performance:

1, particle size: the smaller the particle size, the higher adsorption capacity, but the smaller the particle size, particle strength is lower, affect the service life.

2, raw water PH value: when the PH value is greater than 5, the lower the PH, the higher the adsorption capacity of activated alumina.

3, initial fluoride concentration in the raw water, the higher the initial concentration of fluorine, adsorption capacity is bigger.

4, the chloride ion and sulfate ion.

5, the effects of arsenic: activated alumina adsorption for the arsenic in the water, the accumulation of arsenic on the activated alumina, falling of fluorine ion adsorption capacity and regeneration of elution arsenic ion more difficult.
