ACTIVATED ALUMINA—Defluorination Agent (A-AS-DF)
Activated alumina defluorinated just as the anion exchange resin, but the selectivity is much strong. The defluorination effect of the actived alumina is good. The capacity is stable, the absorbed fluorine is 6400g/cm3. It has high strength, low abrasion, no soften in water, no expansion, no powdery, no crack. It can widely used in the deep drying of cracked gas, ethylene and propylene, hydrogen-generation, air separation, instrument air drying and fluorine treatment for H2O2, also in the absorbing pollution material, such as H2S, SO2, HF and paraffin in the water gas, especially in the drinking water defluorination.

Application
A-AS-04 activated alumina is manufactured from aluminium hydroxide by dehydroxylating it in a way that produces a highly porous material;
A-AS-DF activated alumina is also widely used to remove fluoride from drinking water. Basically, the more alumina in the filter, the less fluoride will be in the final, filtered water.
A-AS-MS is for absorbent H2O2
A-AS-AC is for chlorine absorbent
A-AS-C in hydrogen peroxide production, as a selective adsorbent for many chemicals including,in removal from gas streams .
A-AS-A activated alumina is used as a charge material in foreline traps to prevent generated by from backstreaming into the system
Industry standard HG/T39272007 Activated Alumina is issued by Zhengzhou Mahaco Industrial Co,Ltd
