Activated Alumina

Activated alumina adsorbent is white spherical porous granules, surface smooth, uniform particle size, non-toxic, odorless, tasteless, insoluble in water, alcohol and organic solvents, but insoluble in acids and alkalis. Activated alumina has strong moisture adsorption, does not burst after absorbing water, possesses big mechanical strength, specific surface area and pore volume.

Due to the unique porous bone structure, high specific surface area and in an unstable transition state, activated alumina has biggish activity, strong affinity with active ingredient. Activated alumina has a number of capillary channels, its selective adsorption is not only determined by its micro-holes diameter size, but also according to the polarity of the adsorbed materials. Activated alumina has a strong affinity to water, acetic acid, alkali, etc., is a micro-water depth desiccant also is the adsorbent of polar molecules. Activated alumina monomolecular adsorption layer has high net heat quantity, is very suitable for non-heat regenerative device (pressure swing adsorption device), its dew point temperature is below -70 ℃ and is a highly efficient desiccant.

Yuanying activated alumina defluorination agent is white spherical porous particles, uniform particle size, smooth surface, high mechanical strength, hygroscopicity strong, does not crack and inflate after absorbing water. It is non-toxic, tasteless, odorless, insoluble in water and organic solvents.

Fluorine is one of the trace element necessary for animal and human. Adult normal daily intake should be 2~3 mg, too much or too little can lead to disease, so defluorination is important in drinking water. Activated alumina has good strength, good abrasion resistance, long service life, stable performance, high defluorination capacity, after defluorination the water quality accords with national health standards, so activated alumina is one of the indispensable material in water treatment.
